Answer 1

When you post code, please use[code] and [/code] tags as described in Formatting tips on the message entry page. It makes it much easier to read.
public class TriangleArray {
public static void main(String[] args) {
int[][] triangle = new int[10][];
for(int i=0; i<triangle.length; i++) {
triangle[i] = new int[i+1];
for (int i=0; i<triangle.length; i++) {
for(int j=0; j<triangle.length; j++) {
System.out.print(triangle[i][j]);
System.out.println();
What do you think it does? And we will tell you if you are correct.
