菜鸟求助啊

[yueyemijing]

求0-10之间的偶数的程序，下面程序结果输出不对，刚学面向对象，还是菜鸟不知错哪了……
package zuoye4;
import javax.swing.JOptionPane;

public class oushux {
public static void main(String[] args) {
Oushu myOushu = new Oushu();
String output = "偶数有：";
output += myOushu.getoutput();
JOptionPane.showMessageDialog(null,output,"Output",JOptionPane.INFORMATION_MESSAGE);
}
}
class Oushu{
private int i;
public Oushu(){
}
public int geti(){
for (i=0;i<=10;i++){
if (i%2==0)
continue;
}
return i;
}
public String getoutput(){
return geti()+",";
}
}

coninue到最后啦

[dulang842]

import javax.swing.JOptionPane;

public class FirstSimple {
public static void main(String[] args) {
Oushu myOushu = new Oushu();
String output = "偶数有：";
output += myOushu.geti();
JOptionPane.showMessageDialog(null,output,"Output",JOptionPane.INFORMATION_MESSAGE);
}
}
class Oushu{
static int i;
String out=" ";
public String geti(){
for (i=0;i <=10;i++){
if (i%2!=0)
continue;
else
// a[i]=i;
out+="'"+i;
}
return out;
}
}

你的geti(){方法不对，返回值也有问题

[yueyemijing]

return out;报错 楼上的也不对啊

[dulang842]

我都运行通过了，都可看到结果了，怎么可能不对

[dulang842]

import javax.swing.JOptionPane;

public class FirstSimple {
public static void main(String[] args) {
Oushu myOushu = new Oushu();
String output = "偶数有：";
output += myOushu.geti();
JOptionPane.showMessageDialog(null,output,"Output",JOptionPane.INFORMATION_MESSAGE);
}
}
class Oushu{
static int i;
String out=" ";
public String geti(){
for (i=0;i <=10;i++){
if (i%2!=0)
continue;
else
// a[i]=i;
out+="'"+i;
}
return out;
}
}

}
public String getoutput(){
geti();
return out;
}
}

运不出结果，最主要在于你的变量i是for语句中定议为局部变量，在for语句之外是不存在这个变的，回返回的是空

1楼正确，你肯定要用一个数组来接你返回的数据，
