For my Computer Science lab, I have to make a method that returns a string:
public static String arrayToString(int[] [] a)
a is a two dimensional integer array. The string has to separate each index with a space, and a new line after every row (\n). The rows can't have a space before or after the last value on the row, and the columns can't have a new line before or after the last column. How can I do this? I know it involves a nested for loop but I can't figure out how to code it. Thanks in advance!

"how to code it", how to code what? A for loop? A nested for loop? Or you just need the whole thing written for you?

This is a pretty basic problem. You should get some help from a live person wherever you are a student.
You obviously need 2 nested loops (1 for array row, 1 for column). You want to output each value, providing a space either before or after each element (suggestion: detect the first element in the row and don't print a space), and a new line at the end of each row.
