square.java

本人在JAVA学习中的一点小实验

class Square implements Cloneable{
	double length;
	Square(){
		
	}
	Square(double length){
		this.length=length;
	}
public boolean	equals(Square a){
		if(length==a.length)
		return true;
		else return false;
	}
public String toString(){
	String sq="Square:"+length;
	return sq;
}
}
