Question

public static void main (String[]a){

    int[] x;
    x = new int[10];
    int i;
    int n=0;

    for (i=0;i

        

Answer 1

Yes:

String.format("%01d", x[i]*x[j]); is what you want.

If you're familiar with printf in C then this will be familiar. If not, read the java reference on String.format format strings.

Also, rather than 10 System.out.println statements, you can use a doubly nested loop with two counters. One to count which row you're in j and one for each column i.
