Question

在java编程中怎样输入并输出一个字符char变量(注意：不是字符串！！！)

Answer 1

import java.io.InputStream;
import java.io.IOException;
public class test
{
public static void display(InputStream in)
{
try
{
while(true)
{
int i = in.read();
if(i==-1)break;
char c = (char)i;
System.out.print(c);
}
}
catch(IOException e)
{
e.printStackTrace();
}
}
public static void main(String args[])
{
display(System.in);
}
}
//输入ctrl+z可以终止输入

Answer 2

//接收输入的字符并转成char
Scanner input = new Scanner(System.in);
String c = input.next();
System.out.println(c.toCharArray()[0]);
//将char字符输出
char cc = 'c';
System.out.println(cc);
