字符char的转换

import java.util.;

import java.util.Scanner;

public class Demo1

{

public static void main(String[] args)

{

//定义字符变量

char ch = 'a';

System.out.println(ch);

//错误:不兼容的类型:String无法转换为char

//char ch2 = "a"

//单个的才叫字符

//char ch2 = "abc"

char ch2 = 65;

System.out.println(ch2);

char ch3 = 66;

System.out.println(ch3);

//没有任何的字符编码是负数

//char ch4 = (char)-100;

//System.out.println(ch4);

char ch5 = '李';

System.out.println(ch5);

System.out.println((int)ch5);
