java - 对角线上的矩阵元素

Question

public class Main {
    public static void main(String[] args) {
        int array[][] = {
                {2, 3, 4, 5, 6},
                {2, 3, 4, 5, 6},
                {2, 3, 4, 5, 6},
                {2, 3, 4, 5, 6},
                {2, 3, 4, 5, 6},
        };
        int i, j;
        {
            for (i = 0; i <5; i++) {
                for (j = 0+i; j < 5; j++) {
                    System.out.print(array[i][j] + " ");


                }
                System.out.println();
            }
        }
    }
}

我如何给出高对角线的美学观点？ 换行后需要换行。

Answer 1

例如:

for (i = 0; i <5; i++) {
    for (j = 0; j < 5; j++) {
        if( j >= i ) {
            System.out.printf( "   ");
        else {
            System.out.printf( "%3d", array[i][j] );
        }
     }
     System.out.println();
}
