Question

如图java题，求大神啊！！！

Answer 1

public class Rect {

private double pointX;

private double pointY;

private double width;

private double height;

// 构造函数

public Rect(double pointX, double pointY, double width, double height) {

this.pointX = pointX;

this.pointY = pointY;

this.width = width;

this.height = height;

}

// 计算面积

public double calculateArea(int width, int height) {

return width * height;

}

// 获取x坐标

public double getPointX() {

return pointX;

}

// 获取y坐标

public double getPointY() {

return pointY;

}

// 获取宽度

public double getWidth() {

return width;

}

// 获取高度

public double getHeight() {

return height;

}

}
