teststaticmethod.java

有关于java的小练习

public class TestStaticMethod{
	public static void main(String[] args){
		//ClassA.print();
		Super s=new Sub();
		s.m();//  Super.m();
	}
}
class ClassA{
	int a=10;
	static int b=20;
	public static void print(){
		//System.out.println(a);
		System.out.println(b);	
	}		
	public void print2(){
		System.out.println(a);
		System.out.println(b);
	}
}
class Super{
	public static void m(){
		System.out.println("Super");
	}	
}
class Sub extends Super{
	public static void m(){
		System.out.println("Sub");
	}
}
