interfacedemo.java

java可以实现一些小程序的编写

interface Run{
	int  I=100;
	void printf(String s);
}

class InterfaceDemo1 implements Run{
	int i;
	String s="quickly";
	public void printf(String s){
		System.out.println("in classINterfaceDemo1 Run mothod is: "+s+" run.");
		System.out.println("Const is I="+I);
	}
}


class InterfaceDemo implements Run{
	int I;
	String str="slowly";
	public void printf(String str){
		System.out.println("in classINterfaceDemo1 Run mothod is: "+str+" run.");
		System.out.println("I="+I);
		System.out.println("Const is I="+Run.I);
	}
	public static void main(String args[]){
		InterfaceDemo Ip=new InterfaceDemo();
		Ip.printf(Ip.str);

		InterfaceDemo1 Ip1=new InterfaceDemo1();
		Ip1.printf(Ip1.s);
	}
}
