class Rectangle{
private double weight;
private double height;
public Rectangle(double weight,double height) {
this.weight=weight;
this.height=height;
}
public double perimeter(){
return (weight+height)*2;
}
public double area(){
return weight*height;
}
}
public class Test {
public static void main(String[] args) {
Rectangle rect=new Rectangle(3, 4);
System.out.println("周长："+rect.perimeter());
System.out.println("面积："+rect.area());
}
}
private double weight;
private double height;
public Rectangle(double weight,double height) {
this.weight=weight;
this.height=height;
}
public double perimeter(){
return (weight+height)*2;
}
public double area(){
return weight*height;
}
}

public class Rectabgle{
private double width;
private double height;
public Rectabgle(double width, double height){
this.width = width;
this.height= width;
}
public double getArea(){
return width * height;
}
public double getGirth(){
return 2 * ( width + height );
}
}
