I am not getting what incorrect you have done but still i would like to recommend you that you should try to execute this program as i have tried it and worked well.
Code:
public class PascalTriangle {
public static void main(String args[]) {
int x = 6;
int triangle[][] = new int[x][x];
for (int i = 0; i < x; i++) {
for (int j = 0; j < x; j++) {
triangle[i][j] = 0;
}
}
for(int i = 0; i < x; i++) {
triangle[i][0] = 1 ;
}
for (int i = 1; i < x; i++) {
for (int j = 1; j < x; j++) {
triangle[i][j] = triangle[i-1][j-1] + triangle[i-1][j];
}
}
for (int i = 0; i < x; i++) {
for(int j=0;j<=i;j++) {
System.out.print(triangle[i][j]+ " ");
}
System.out.println();
}
}
}
