在Java的GUI编程中,如何使用GUI显示不同的形状?
以下示例演示如何使用Arc2D
,Ellipse2D
,Rectangle2D
,RoundRectangle2D
类显示不同的形状。
package com.yiibai;
import java.awt.Shape;
import java.awt.geom.*;
public class DisplayDifferentShapes {
public static void main(String[] args) {
int x1 = 1, x2 = 2, w = 3, h = 4, x = 5, y = 6, y1 = 1, y2 = 2, start = 3;
Shape line = new Line2D.Float(x1, y1, x2, y2);
Shape arc = new Arc2D.Float(x, y, w, h, start, 1, 1);
Shape oval = new Ellipse2D.Float(x, y, w, h);
Shape rectangle = new Rectangle2D.Float(x, y, w, h);
Shape roundRectangle = new RoundRectangle2D.Float(x, y, w, h, 1, 2);
System.out.println("Different shapes are created!");
}
}
上述代码示例将产生以下结果。
Different shapes are created!
