这个哪里出错了呢 大牛给看看哈 ！！！！
class Cycle
{
private double radius;
public Cycle(double radius)
{
this.radius=radius;
}
public Cycle compare(Cycle c)
{
//程序代码
return (this.radius>c.radius) ? this : c ;
}

}
class TD
{
public static void main(String[] args)
{
Cycle c1=new Cycle(1.0);
Cycle c2=new Cycle(2.0);
Cycle c;
c=c1.compare(c2);

if(c==c1)
System.out.println("圆1的面积比较大");
else
System.out.println("圆2的面积比较大");

}
}

[解决办法]

Java code

class Circle {    private double radius;    public Circle(double radius) {        this.radius = radius;    }    public Circle compare(Circle c) {        // 程序代码        return (this.radius > c.radius) ? this : c;    }}class TD {    public static void main(String[] args) {        Circle c1 = new Circle(1.0);        Circle c2 = new Circle(2.0);        Circle c;        c = c1.compare(c2);        if (c == c1)            System.out.println("圆1的面积比较大");        else            System.out.println("圆2的面积比较大");    }}

对，不必加其实也可以，目测楼主是不是吧文件名写错了
[解决办法]
我晕，我在  自己的eclipse上面运行，木有错误啊

结果是：圆2的面积比较大

Java code
package com;public class Cycle {    private double radius;    public Cycle(double radius)    {    this.radius=radius;        }        public Cycle compare(Cycle c)    {    //程序代码        return (this.radius>c.radius) ? this : c ;    }}
