Java中看程序写结果:子类调用父类 static方法

===

package test1;

class A {
	public static void print() {
		System.out.println(A.class); // here
	}
}

-------------------------------

class B extends A {

}

--------------------------------

public class Main {
	public static void main(String[] args) {
		B.print();		
	}
}

--------------------------------

• resault : class test1.A

Cannot use super in a static context！

package test1;

class A {
	public static void print() {
		System.out.println(A.class); // here
	}
}
//-------------------------------
class B extends A {
      [color=red]  //此处在静态方法中调用super[/color]
	public static void print() {
	//	super.print();---------------->error!
        //                           Cannot use super in a static context！
		System.out.println(B.class); // here
	}
}
//--------------------------------
public class Main {
	public static void main(String[] args) {
		System.out.println(Main.class); // here
		B.print();
		
	}
}

--------------------------------

• 运算结果：
• class test1.Main
• class test1.B
