问一个JAVA编程的问题

import java.io.*;

public class SimpleCharInOut{

char c;

System.out.print ("Enter a character please:");

try{

c=(char)System.in.read();

}

catch(IOException e){

System.err.println(e.toString());

}

System.out.println("You have entered character"+c);

}

}

这段代码编译的时候,系统报有5个错误,麻烦高手看一下都哪里出错了好么,谢谢!~

package com.news;

import java.util.StringTokenizer;

import java.io.*;

public class A{

public void mian(){

char c='a';

System.out.print ("Enter a character please:");

try{

c=(char)System.in.read();

}

catch(IOException e){

System.err.println(e.toString());

}

System.out.println("You have entered character"+c);

}

}

你的表达式应该放在一个方法里面

而且你多了一个}

c应该有初始值
