java - 将 While 循环与 g.drawPolygon 代码结合使用

Question

所以这是我并排制作一堆表格的代码。(我仍然是初学者)

import java.applet.Applet;
import java.awt.*;

public class Test extends Applet{

public void init() {
setSize(500, 225);
}

public void paint (Graphics g){

//Desk #1
int [ ] x8 = {430, 430, 351, 351};
int [ ] y8 = {200, 185, 185,200};
g.drawPolygon(x8, y8, 4);

//Desk #2
int [ ] x9 = {351, 351, 272, 272};
int [ ] y9 = {200, 185, 185, 200};
g.drawPolygon(x9, y9, 4);

//Desk #3
int [ ] x10 = {272, 272, 193, 193};
int [ ] y10 = {185, 200, 200, 185};
g.drawPolygon(x10, y10, 4);

//Desk #4
int [ ] x11 = {193, 193, 114, 114};
int [ ] y11 = {185, 200, 200, 185};
g.drawPolygon(x11, y11, 4);

//Desk #5
int [ ] x12 = {114, 114, 35, 35};
int [ ] y12 = {185, 200, 200, 185};
g.drawPolygon(x12, y12, 4);

}
}

我想要做的只是制作一个 while 循环，这样我就不需要做所有这些序列垃圾，有人可以为我制作一个有效的 while 循环代码并教我他们是如何做到的吗，我已经被这个问题困扰了很长时间了。

您也许可以使用内部类来存储坐标。我不确定您是否想专注于多维数组。

public class Test extends Applet {

    Poly desk1 = new Poly(new int[] {430, 430, 351, 351}, new int[] {200, 185, 185,200});
    Poly desk2 = new Poly(new int[] {351, 351, 272, 272}, new int[] {200, 185, 185, 200});
    Poly desk3 = new Poly(new int[] {272, 272, 193, 193}, new int[] {185, 200, 200, 185});
    Poly desk4 = new Poly(new int[] {193, 193, 114, 114}, new int[] {185, 200, 200, 185});
    Poly desk5 = new Poly(new int[] {114, 114, 35, 35}, new int[] {185, 200, 200, 185});

    Poly[] desks = new Poly[] {desk1, desk2, desk3, desk4, desk5};

    public void init() {
        setSize(500, 225);
    }

    public void paint (Graphics g) {
        for (int i = 0; i < desks.length; i++) {
            g.drawPolygon(desks[i].xs, desks[i].ys, 4);
        }
    }

    private static class Poly {
        // public fields are sometimes frowned upon,
        // but for a private class and a simple example
        public int[] xs;
        public int[] ys;

        public Poly(int[] xs, int[] ys) {
            this.xs = xs;
            this.ys = ys;
        }
    }

}
