import java.io.*;
public class InOut
{
public static void main(String args[])
{
char c;
System.out.print("enter a character please:");
try{
c=(char)System.in.read();
}catch(IOException e){};
System.out.println("you'v entered charactor "+c);
}
}


//编译始终通不过，报错如下：
--------------------Configuration: j2sdk1.4.2 <Default>--------------------
D:\java\Java Code\InOut.java:11: variable c might not have been initialized
System.out.println("you'v entered charactor "+c);

我开始以为是版本不同的缘故，但我用各个版本进行了调试，同样出现了这个问题！请问这是什么原因咯！

局部变量要明确先初始化，例如c＝'a';

public class InOut
{
public static void main(String[] args)
{
System.out.print("enter a character please:");
try{char c;
c=(char)System.in.read();
}catch(Exception e){}
System.out.println("you'v entered charactor "+ "c");
}
局部变量包含到try catch块中，并且catch后面的{}不加分号。
}
