我试图在eclipse中运行一个使用名为getArea(一个对象)的方法的代码。我目前收到错误说
对于getArea(ComparableRectangle)类型，方法RectangleTest未定义
这是RectangleTest的代码 -
package geometry;
import java.awt.Rectangle;
public class RectangleTest extends Rectangle {
/**
*
*/
private static final long serialVersionUID = -3282103336310735942L;
public static void main(String args[]) {
ComparableRectangle rect01 = new ComparableRectangle(5, 4);
ComparableRectangle rect02 = new ComparableRectangle(6, 8);
System.out.println("Area: " + getArea(rect01));
}
}
这是ComparableRectangle的代码。
package geometry;
import java.awt.Rectangle;
public class ComparableRectangle extends Rectangle implements Comparable {
private int width;
private int height;
public ComparableRectangle(int w, int h) {
width = w;
height = h;
}
public double getArea(ComparableRectangle rect) {
return width*height;
}
public boolean compareTo(ComparableRectangle rect1, ComparableRectangle rect2) {
if(rect1.width == rect2.width && rect1.height == rect2.height) {
return true;
}
else {
return false;
}
}
@Override
public int compareTo(Object o) {
// TODO Auto-generated method stub
return 0;
}
}
我如何澄清rect01是一个可比较的矩形？
