import java.io.*;
public class SimpleCharInOut
{
     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've enter character"+c);
            }
}

怎么这样改会行:

import java.io.*;
public class Sim
{
     public static void main(String args[])
           {
                 char c=1;    //必须先进行初始化
                 System.out.print("enter a character please:");
                 try{
                       c=(char)System.in.read();
                  }catch(IOException e){};
                   System.out.println("you've enter character"+c);
            }
}
