大虾们,help me!这个错误搞了我一下午.

[opou]

import java.util.*;
public class TestVector {

public static void main(String[] args) {
int b = 0;

Vector v = new Vector();
System.out.println("please enter number:");
int sum = 0;
while(true)
{
try
{
b = System.in.read();
}
catch(Exception e)
{
e.printStackTrace();
}
if (b == '\r'||b == '\n')
break;
else
{
int num = b - '0';
v.addElement(new Integer(num));
}

}
//int sum = 0;
Enumeration e = v.elements();
while(e.hasMoreElements())
{
Integer intObj = (Integer)e.nextElement();
sum += intObj.intValue();
}
}
System.out.println(sum);
}
错误是:
--------------------Configuration: TestVector - JDK version 1.5.0 <Default> - <Default>--------------------
F:\javawork\lesson2\TestVector.java:37: <identifier> expected
System.out.println(sum);

方到main里面好吗？

[boyu_song]

System.out.println(sum);
写错地方了

[wenger]

import java.util.*;
public class TestVector {

public static void main(String[] args) {
int b = 0;

Vector v = new Vector();
System.out.println("please enter number:");
int sum = 0;
while(true)
{
try
{
b = System.in.read();
}
catch(Exception e)
{
e.printStackTrace();
}
if (b == '\r'||b == '\n')
break;
else
{
int num = b - '0';
v.addElement(new Integer(num));
}

}
//int sum = 0;
Enumeration e = v.elements();
while(e.hasMoreElements())
{
Integer intObj = (Integer)e.nextElement();
sum += intObj.intValue();
}
System.out.println(sum); //put it here
}

}

System.out.println(sum);
要放到 main()方法的里面!!

同意！必须注意！变量的有效范围！

我无话可说，楼主1个月后再来看看你这篇帖子，就能体会到有多么搞笑了。
