java - How to refer particular class with conflicting names?

Question

I am not able to create a java.awt.Rectangle object in following code. However, I can still create Rectangle object... Please explain why is it so?

package examples;
import java.awt.*;
public class Rectangle {
    public static void main(String[] args) {
        java.awt.Rectangle rect = new Rectangle();
        System.out.println(rect.toString());    
    }
}

Answer 1

请解释为什么会这样？

您 正在创建Rectangle类的实例，但试图将其分配给java.awt.Rectangle变量。您可以将其更改为：

java.awt.Rectangle rect = new java.awt.Rectangle();

当然，您应该首先尽可能避免此类命名冲突，但您始终可以使用完全限定名称，只要该类位于包中即可。（默认包中的事情变得更加棘手，您应该避免这种情况。）

Answer 2

您的班级从包中Rectangle隐藏了班级。您需要完全限定的名称：Rectanglejava.awt

java.awt.Rectangle rect = new java.awt.Rectangle();
