java匿名内部类

标签：java.匿名内部类

java匿名内部类一般是没有变量指向的对象，只能使用一次

如下代码，为了使用抽象类People的eat方法还要去继承然后复写eat方式，非常麻烦。对于接口也是如此。

package com.lubby.nosynchronizedtest;

 public  abstract class People {
public abstract void eat() ;
}<pre name="code" class="java">package com.lubby.nosynchronizedtest;

public class Teacher extends People {

	@Override
	public void eat() {
		System.out.println("老师正在吃饭");
	}

	public static void main(String[] args) {
		People people = new Teacher();
		people.eat();

	}

}

package com.lubby.nosynchronizedtest;

public class Teacher {

	public static void main(String[] args) {
		new People() {
			@Override
			public void eat() {
				System.out.println("我正在吃饭");
			}
		}.eat();
	}
}

package com.lubby.nosynchronizedtest;

public class Teacher {

	public static void main(String[] args) {
		Thread thread1 = new Thread() {
			public void run() {
				System.out.println("线程1正在跑");
			}
		};
		thread1.start();
	}
}

package com.lubby.nosynchronizedtest;

public class Teacher {

	public static void main(String[] args) {
		Runnable runable = new Runnable() {
			@Override
			public void run() {
				System.out.println("run.......");
			}
		};
		Thread thread = new Thread(runable);
		thread.start();
	}
}
