juxing.java

用java实现输入2个数 求这两个数相加

class rectangle
{
	int c,k;
	rectangle(int a,int b){
		c=a;k=b;
		}
	int girth(int a,int b){
		int girthc;
		girthc=2*a+2*b;
		return girthc;
		}
	int area(int a,int b){
		int area1;
		area1=a*b;
		return area1;
		}
	}
	
public class juxing{
	public static void main(String[] args)
	{
		rectangle z=new rectangle( );
		System.out.println("The zhouchang is:"+z.girth(10,8));
		System.out.println("The mianji is:"+z.area(10,8));
		}
	}
