Share the Java print simple graphics implementation code

We usually use the drawing tool to draw simple graphics, today we use Java to print some simple graphics

The implementation code is as follows

 package test;

public class Array {
  public static void main(String[] args) {
    //Print rectangle
    int[] a = new int[10];
    for(int i=0 ;i<a.length;i++){
      for(int j=0;j<a.length;j++){
        System.out.print("*");
      }
    System.out.println();
    }
    System.out.println();
    
    //Print an inverted right triangle
    int[] b = new int[10];
    for(int i=0 ;i<b.length;i++){
      for(int j=0;j<b.length-i;j++){
        System.out.print("*");
      }
    System.out.println();
    }
    System.out.println();
    
    //Another kind of inverted right triangle
    int[] e = new int[10];
    for(int i=0;i<e.length;i++){
      for(int j=0;j<i;j++){
        System.out.print(" ");        
      }
      for(int m=0;m<e.length-i;m++){
        System.out.print("*");
      }  
    System.out.println();
    }
    System.out.println();
    
    //Print out the parallelogram

}

The above is the entire content of this article, this small program has a strong universality, I hope to help you learn.
