squaretest.java

本人在JAVA学习中的一点小实验

public class SquareTest{
	public static void main(String args[]){
		Square a=new Square(10);
		Square b=new Square(20);
		System.out.println(""+a.length);
		if(a.equals(b))
		System.out.println("equals");
		else 	System.out.println("not equals" );
	    String sq=a.toString();
		System.out.println(sq);
	}
}
