staticdemo3.java

java可以实现一些小程序的编写

class A1{
	 int x=10;
	 void show(){
		System.out.println("father");
	}
}

class StaticDemo3 extends A1{
	static int  x=100; //加不加static都可编译通过, ；int x 正确
    
      void show(){
    	System.out.println("son");
    }
    void show(int x){ //去掉参数就必须加上static
		System.out.println("x=  no static "+x);
	}
	static void show(float f) {
		System.out.println("f="+f);
	}
	
	void show(double d) {
		System.out.println("d="+d);
	}
	public static void main(String s[]){
		//System.out.println(A1.x);
		//show();
		show(55.00f);
		StaticDemo3  oo=new StaticDemo3();
		System.out.println(oo.x);
		//A1.show();
		oo.show(888);
		oo.show(33.0000);
	}
