Share the implementation code for printing simple graphics in java

We usually use drawing tools 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) {
    //打印长方形
    int[] a = new int[10];
