New to MIPS - Java to MIPS Translation Issues

To be honest, this isn't my first attempt to post and get help, but the other site decided to close my post because it wasn't a good enough question and because I decided to bump it. Be awesome if you could help me out, been trying to figure this out.

When I go to assemble and run the code, the program loops back up to the user prompt over and over again. I can only edit the Search section of the code. Basically the program should take the user input and tell where in the list the number that the is, if the number is in the list. When I ran it line by line, it went past the part it was stuck at, but it just printed the entire list. You will be considered awesome and get an internet high five from me. :cheers:

Here is the MIPS Code:

Code:

		.data
list:		.word 5
		.word 7
		.word 4
		.word 6
		.word 3
		.word 8
		.word 2
		.word 9
		.word 0
		.word 30
		.word 31
		.word 39
		.word 32
		.word 38
		.word 33
		.word 37
		.word 34
		.word 36
		.word 35
		.word 20
		.word 21
		.word 29
		.word 22
		.word 28
		.word 23

		.word 1			# last array element
		.word -1			# not part of array
prompt1:	.asciiz "\nPlease enter an array element: "
prompt2:	.asciiz "\nPlease enter a search target: "
space:	.asciiz " "
nfound:	.asciiz "\nThe target was not found."
found:	.asciiz "\nThe target was found at array location "

		.text

		addi $t0, $t0, 1		#

search:		add $t4, $t1, $t1
		addi $t5, $t1, 1
		sgt $t1, $t4, $t5
		addi $t4, $t1, 1		
		add $t5, $t1, $t1
		add $t1, $t1, 1
		blt $t3, $t1, search
		sub $t3, $t3, 1
		add $t0, $t0, 1
		blt $t2, $t0, search
		
print:		addi $v0, $zero, 1	# [print]
		sll $t7, $t0, 2		#

		syscall
		addi $t0, $t0, 1		#
		ble $t0, $t2, print	#

end:		addi $v0, $zero, 10	# [end]
		syscall

Here is the Java code that I am to translate from:

Code:

	import java.io.*;
	
	public class CIS2233StarterCode2Java {
	
	public static void main (String [] args) throws IOException {
	
	BufferedReader kbd = new BufferedReader (new InputStreamReader (System.in));
	int [] list = {5,7,4,6,3,8,2,9,0,20,21,29,22,28,23,27,24,26,25,30,31,39,32,38,33,37,34,36,35,10,11,19,12,18,13,17,14,16,15,1};
	String prompt1 = "\nPlease enter an array element: ";
	String prompt2 = "\nPlease enter a search target: ";
	String space = " ";
	String nfound = "\nThe target was not found.";
	String found = "\nThe target was fount at array location ";
	int t0 = 0;
	int t1 = 0;
	int t2 = 39;
	int t3 = 39;
	int t4;
	int t5;
	int t6;
	int a0;
	int v0;
	// address calculation register t7
	// base address of array register t8
	// address calculation register t9
	do {
		System.out.print (prompt1);
		v0 = Integer.parseInt(kbd.readLine());
		list [t0] = v0;
		t0 ++;
	} while (t0 <= t2);
	t0 = 0;
	do {
		t1 = 0;
		do {
			t4 = list [t1];
			t5 = list [t1 + 1];
			if (t4 > t5) {
				list [t1 + 1] = t4;
				list [t1] = t5;
			}
			t1 ++;
		} while (t1 < t3);
		t3 --;
		t0 ++;
	} while (t0 < t2);
	t0 = 0;
	do {
		a0 = list [t0];
		System.out.print (a0);
		System.out.print (space);
		t0 ++;
	} while (t0 <= t2);
        }
        }

 

Update to the search section. Still could use the help as the code won't go past the read section.

5 forum posts and can't get any help. All I have gotten is snobby remarks. Should of gotten something by now.

 

Narrowed down to this line

Code:

    		ble $t0, $t2, read	#

 

Never mind scratch that. Seriously just figured it out. The instructor made it so that the user has to enter 39 prompts.

I have a new error though

Here is the updated MIPS Code

I am now getting an error message, so I have made a bit of progress.
Not quote sure what to make of this message I am getting with the runtime error saying : fetch address not aligned on word boundary 0x00000001

 

I should probably say it is on line 139

Code:

lw $t5, 1($t7)

 

how do i say this in MIPS?

Code:

t5 = list [t1 + 1];
