Java Programming/Keywords/char

char is a keyword. It defines a character primitive type. char can be created from character literals and numeric representation. Character literals consist of a single quote character (') (ASCII 39, hex 0x27), a single character, and a close quote ('), such as 'w'. Instead of a character, you can also use unicode escape sequences, but there must be exactly one.

Syntax:

char variable name₁ = 'character₁';

Example Code section 1: Three examples.

charoneChar1='A';
charoneChar2=65;
charoneChar3='\u0041';
System.out.println(oneChar1);
System.out.println(oneChar2);
System.out.println(oneChar3);

Computer code Output for Code section 1

65 is the numeric representation of character 'A' , or its ASCII code.

The nominal wrapper class is the java.lang.Character class when you need to store a char value but an object reference is required.

Example Code section 2: char wrapping.

charaCharPrimitiveType='A';
CharacteraCharacterObject=aCharPrimitiveType;
