Rectangle类的代码如下:
```
public class Rectangle {
private int length;
private int width;
public Rectangle(int length, int width) {
this.length = length;
this.width = width;
}
public int getLength() {
return length;
}
public void setLength(int length) {
this.length = length;
}
public int getWidth() {
return width;
}
public void setWidth(int width) {
this.width = width;
}
public int getPerimeter() {
return 2 * (length + width);
}
public int getArea() {
return length * width;
}
public static void main(String[] args) {
Rectangle rectangle = new Rectangle(10, 5);
System.out.println("矩形的周长为:" + rectangle.getPerimeter());
System.out.println("矩形的面积为:" + rectangle.getArea());
}
}
```
输出结果为:
```
矩形的周长为:30
矩形的面积为:50
```
