Java中的char和Character之间有什么区别？ [英] What is the difference between char and Character in Java?

问题描述

我需要知道在Java中的char和Character之间的区别是什么，因为当我在做一个java程序时，char工作时字符不工作。

char，

的示例

  char ch ='a'; 
  

角色示例，

  Character.toUpperCase（ch）; 
  

将'a'转换为'A'

I need to know what is the difference between char and Character in Java because when I was making a java program, the char worked while the Character didn't work.

解决方案

char is a primitive type that represents a single 16 bit Unicode character while Character is a wrapper class that allows us to use char primitive concept in OOP-kind of way.

Example for char,

char ch = 'a';

Example of Character,

Character.toUpperCase(ch);

It converts 'a' to 'A'
