我希望这个程序打印三角形的数字

Question

我想在数字前放置空格以获得三角形形状！

package Za1;

import java.util.Scanner;

public class Za1 {




public static void main(String[] args) {

 int i=-1;
 for (int j=0;j<11;j+=2){
  i++;
  for (int z=0;z<=j;z++){
      System.out.printf("%d",i);

  }System.out.println();
}
}

 }

Just small change in your code-

public static void main(String[] args) {

    int i = -1;
    for (int j = 0; j < 11; j += 2) {
        i++;
        for (int k = i; k < 5; k++) //small change
            System.out.print(" "); //small change
        for (int z = 0; z <= j; z++) {
            System.out.printf("%d", i);

        }
        System.out.println();
    }
}
