How to make a Rect in Java?
问题
我已经在互联网上扫描了半个小时，而且人们建议的矩形方法不起作用，所以我想知道你们会建议什么。

以下是您要求的翻译内容：
这里有一个由二维网格构成的简单代码
import java.awt.Graphics;
import javax.swing.JComponent;
import javax.swing.JFrame;
class MyCanvas extends JComponent {
public void paint(Graphics g) {
g.drawRect(10, 10, 200, 200);
}
}
public class DrawRect {
public static void main(String[] a) {
JFrame window = new JFrame();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setBounds(30, 30, 300, 300);
window.getContentPane().add(new MyCanvas());
window.setVisible(true);
}
}
输出:
否则，可以使用 Graphics 对象的 drawRect() 方法。该方法如下：
drawRect(int x, int y, int width, int height)
它使用当前的画笔颜色绘制矩形的轮廓。矩形的左边和右边边缘分别位于 x 和 x + width 处。矩形的顶部和底部边缘分别位于 y 和 y + height 处。
该方法也可用于绘制正方形。该小程序在整个绘图区域周围绘制一个矩形，然后在中心放置另一个矩形。

The simple code in here which is made by a 2D grid
import java.awt.Graphics;
import javax.swing.JComponent;
import javax.swing.JFrame;
class MyCanvas extends JComponent {
public void paint(Graphics g) {
g.drawRect (10, 10, 200, 200);
}
}
public class DrawRect {
public static void main(String[] a) {
JFrame window = new JFrame();
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setBounds(30, 30, 300, 300);
window.getContentPane().add(new MyCanvas());
window.setVisible(true);
}
}
Output :
Otherwise use the drawRect() method of a Graphics object. This method looks like:
drawRect(int x, int y,
int width, int height)
It draws the outline of a rectangle using the current pen color. The left and right edges of the rectangle are at x and x + width respectively. The top and bottom edges of the rectangle are at y and y + height respectively.
This method is also used to draw a square. This applet draws a rectangle around the entire drawing area, then puts another rectangle in the center.
