super语句，和方法覆盖

super用于调用超类方法

public interface interfacetest {
	public void public1();
	public void public2();
}

public class subclasstest extends superclasstest{

	@Override
	public void public1() {
		super.public1();
		//System.out.println("subclass public1");
		
	}

	@Override
	public void public2() {
		System.out.println("subclass public2");
	}
	
	public static void main(String[] args) {
		subclasstest s = new subclasstest();
		s.public1();
	}

}

public class superclasstest implements interfacetest{

	@Override
	public void public1() {
		//System.out.println("superclass public1");
		public2();
	}

	@Override
	public void public2() {
		System.out.println("superclass public2");
		
	}

}

1：方法覆盖后，可以认为超类覆盖的方法挂掉了，覆盖的意思很明显哈

2：被覆盖的方法用super方式复活
