im really new to progeramming java im trying to do the following "SalesStaff inherits from Employee and represents an employee who has a basic yearly salary, paid weekly over 52 weeks, but who can also earn a weekly bonus depending on performance during the weekThe employee is awarded bonus points for the week and each bonus point earns £20 extra on the weekly pay for that week only" i just tired the following code , Code: private double bonusPoints (){ return super inputSalary / 52.0 + bonusPoints * 20; } but it comes up with the following errors Code: SalesStaff.java:13: '.' expected return super inputSalary / 52.0 + bonusPoints * 20; ^ SalesStaff.java:13: <identifier> expected return super inputSalary / 52.0 + bonusPoints * 20; ^ 2 errors
this is the code for all the class Code: public class SalesStaff extends Employee { //instance variables double bonusPoints; //constructor public SalesStaff (String inputName, String inputSurname, String inputPayRef, double inputSalary,String inputCar) { super (inputName , inputSurname , inputPayRef ,inputSalary); } //other methods private double bonusPoints (){ return super inputSalary / 52.0 + bonusPoints * 20; } public void showDetails(){ super.showDetails(); } }//End of class definition
hi chasey, I guess you forgot a . (dot) after super keyword in this line : return super inputSalary / 52.0 + bonusPoints * 20; just replace the above line with this : return super.inputSalary / 52.0 + bonusPoints * 20; This will solve your purpose, you can send the code for Employee class also if there are any further issues. Thanks and Regards Amit Dave
i just tried Code: private double bonusPoints (){ return super.getSalary / 52.0 + bonusPoints * 20; } but it come up with the following error Code: SalesStaff.java:13: cannot resolve symbol symbol : variable getSalary location: class Employee return super.getSalary / 52.0 + bonusPoints * 20; ^ i aslo tired this Code: return this.getSalary / 52.0 + bonusPoints * 20; } but this came up with following errror Code: SalesStaff.java:13: cannot resolve symbol symbol : variable getSalary location: class SalesStaff return this.getSalary / 52.0 + bonusPoints * 20; ^ im very new to java please help here is the emplyee classs Code: public class Employee { //instance variables private String fName; private String sName; private String payReference; private double annualSalary; //constructor public Employee (String inputName, String inputSurname, String inputPayRef, double inputSalary) { fName = inputName; sName = inputSurname; payReference = inputPayRef; annualSalary = inputSalary; } //The next 4 methods are ACCESSOR methods public String getfName(){ return fName; } public String getsName(){ return sName; } public String getPayReference(){ return payReference; } public double getSalary(){ return annualSalary; } //The next 4 methods are SETTING methods public void setName(String newName){ fName = newName; } public void setsName(String newsName){ sName = newsName; } public void setPayReference(String newPayRef){ payReference = newPayRef; } public void setSalary(double newSalary){ annualSalary = newSalary; } public void showDetails(){ System.out.println("Employee Name : " + this.getfName() ); System.out.println("Employee Surname : " + this.getsName() ); System.out.println("Pay Reference : " + this.getPayReference()); System.out.println("Annual Salary : £ " + this.getSalary()); } }//End of class definition
Hi Just copy this code below in a java file and name it "SalesStaff.java" and try to compile it. It will compile successfully as it did for me. Code: class Employee { //instance variables private String fName; private String sName; private String payReference; private double annualSalary; //constructor public Employee (String inputName, String inputSurname, String inputPayRef, double inputSalary) { fName = inputName; sName = inputSurname; payReference = inputPayRef; annualSalary = inputSalary; } //The next 4 methods are ACCESSOR methods public String getfName(){ return fName; } public String getsName(){ return sName; } public String getPayReference(){ return payReference; } public double getSalary(){ return annualSalary; } //The next 4 methods are SETTING methods public void setName(String newName){ fName = newName; } public void setsName(String newsName){ sName = newsName; } public void setPayReference(String newPayRef){ payReference = newPayRef; } public void setSalary(double newSalary){ annualSalary = newSalary; } public void showDetails(){ System.out.println("Employee Name : " + this.getfName() ); System.out.println("Employee Surname : " + this.getsName() ); System.out.println("Pay Reference : " + this.getPayReference()); System.out.println("Annual Salary : £ " + this.getSalary()); } }//End of class definition public class SalesStaff extends Employee { //instance variables double bonusPoints; //constructor public SalesStaff (String inputName, String inputSurname, String inputPayRef, double inputSalary,String inputCar) { super (inputName , inputSurname , inputPayRef ,inputSalary); } //other methods private double bonusPoints (){ return super.getSalary() / 52.0 + bonusPoints * 20; } public void showDetails(){ super.showDetails(); } }//End of class definition Regards Amit Dave
this is what i have so far on a test class can someone help with it , is there a way of of test all the the class in test? im never done one before Code: public class EmpolyeeTestClass { public static void main(String[] args) { } }
Can you explain a bit more about your test routine. The code you have is just what is the minimum needed to start the execution.
hi i want to test the emplyee class , i want to test the setting of the names and to see if they work, then i want to test the other class
this is what i have done can help me finish it? Code: public class EmpolyeeTestClass { public static void main(String[] args) { System.out.println ("Please type the emplyee name:"); String fname = EasyIn.getString( ); System.out.println ("Please type the cemplyee secound name :"); String sName = EasyIn.getString( ); } } the easy in is a class that i got with the cd that came with the book , can you help show the details i put e.g emplyee name
Hi Chasey, It is very difficult to tell you how to test EasyIn class without knowing what it contains. Kindly tell us in details what all methods it have, whether they are static or not and what they do. Or at least give the code of EasyIn class so that we could help you properly to solve your query. Regards Amit Dave
here the info on easy in class Class EasyIn java.lang.Object | +--uwejava.EasyIn -------------------------------------------------------------------------------- public abstract class EasyIn extends java.lang.Object This class contains easy to use input methods as described in the the text book "Java - The First Semester" by Quentin Charatan and Aaron Kan. For convenience, the class has been moved into the "uwejava" package, so you must put the following line at the start of every program that uses it: import uwejava.*; Note that you must not/cannot create any objects of this class, so a typical method call has the form: String s = EasyIn.getString (); -------------------------------------------------------------------------------- Constructor Summary protected EasyIn() Note that you can't create any objects of this class and so it is not necessary to use the constructor Method Summary static byte getByte() Read a small number from the keyboard and return it as a byte (8 bit) value. static char getChar() Read a single character from the keyboard and return it as a char value. static double getDouble() Read a floating point number number from the keyboard and return it as a double value. static float getFloat() Read a floating point number number from the keyboard and return it as a float value. static int getInt() Read a number from the keyboard and return it as an int value static long getLong() Read a number from the keyboard and return it as a long integer (64 bit) value. static short getShort() Read a number from the keyboard and return it as a short integer (16 bit) value. static java.lang.String getString() Get a complete line of input from the keyboard and return it as a String value. static void pause() Wait until the user presses [return] static void pause(java.lang.String messageIn) Write the specified message and wait until the user presses [return] Methods inherited from class java.lang.Object clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait Constructor Detail EasyIn protected EasyIn()Note that you can't create any objects of this class and so it is not necessary to use the constructor Method Detail getString public static java.lang.String getString()Get a complete line of input from the keyboard and return it as a String value. Example call: String str = EasyIn.getString (); -------------------------------------------------------------------------------- getInt public static int getInt()Read a number from the keyboard and return it as an int value Example call: int i = EasyIn.getInt (); -------------------------------------------------------------------------------- getByte public static byte getByte()Read a small number from the keyboard and return it as a byte (8 bit) value. Note that this method is not recommended for general use by novice programmers. In most cases, getInt () is preferred Example call: byte b = EasyIn.getByte (); -------------------------------------------------------------------------------- getShort public static short getShort()Read a number from the keyboard and return it as a short integer (16 bit) value. Note that this method is not recommended for general use by novice programmers. In most cases, getInt () is preferred Example call: short s = EasyIn.getShort (); -------------------------------------------------------------------------------- getLong public static long getLong()Read a number from the keyboard and return it as a long integer (64 bit) value. Note that this method is not recommended for general use by novice programmers. In most cases, getInt () is preferred Example call: long l = EasyIn.getLong (); -------------------------------------------------------------------------------- getDouble public static double getDouble()Read a floating point number number from the keyboard and return it as a double value. Example call: double d = EasyIn.getDouble (); -------------------------------------------------------------------------------- getFloat public static float getFloat()Read a floating point number number from the keyboard and return it as a float value. Note that this method is not recommended for general use by novice programmers. In most cases, getDouble () is preferred Example call: float f = EasyIn.getFloat (); -------------------------------------------------------------------------------- getChar public static char getChar()Read a single character from the keyboard and return it as a char value. Example call: char ch = EasyIn.getChar (); -------------------------------------------------------------------------------- pause public static void pause()Wait until the user presses [return] If you put a call to this method as the final statement of your main () method, then the program window will remain open until you enter [return] Example call: EasyIn.pause (); -------------------------------------------------------------------------------- pause public static void pause(java.lang.String messageIn)Write the specified message and wait until the user presses [return] If you put a call to this method as the final statement of your main () method, then the program window will remain open until you enter [return] Example call: EasyIn.pause ("Press RETURN to continue");
