    wrote a java to read integer Command line argument program which would perform some opertions as follows:
    Code:
    import java.lang.Math;
    class ComLineNum 
    {
        public static void main(String[] args) 
        {
            int result=0,firstArg=0,secArg=0;
            char operArg='\0';
            try
            {
                firstArg = Integer.parseInt(args[0]);
                operArg = args[1].charAt(0);
                secArg=Integer.parseInt(args[2]);            
            }
            catch (Exception e){}
            switch(operArg)
            {
                case '+' : result =firstArg + secArg;
                           break;
                case '-' : result =firstArg - secArg;
                           break;
                case '*' : result =(firstArg * secArg);
                           break;
                case '/' : result =firstArg / secArg;
                           break;
                case '%' : result =firstArg % secArg;
                           break;
                case '^' : result =(int)Math.pow(firstArg ,secArg);
                           break;
                default:   System.out.println ("Default");
                           break;
            }
            System.out.println(result);
        }
    } 
    The output is:
    F:\JAVA>java ComLineNum 23 + 3
    26

    But the problem is for the following input:

    F:\JAVA>java ComLineNum 23 * 3
    Default
    0

    please hell
