Output:

The character literal is enclosed in single quote and string literal is put in double quotes. The boolean type can have any of the 2 literal values i.e. true or false. Java also has support for null literal but it cannot be used with primitives but can be used with reference types.Let’s understand it better with an example.

//Prg3.java

//Description : Literal usage with char,String and boolean type.

class Program {

static void prgOps() {

char c = 'a';

String str = "Vanakkam Java";

// c=null; // error cannot be used with primitives

str = null;

boolean b = true;

// b= null; // error

System.out.println("Char literal:"+c);

System.out.println("String literal:"+str);

System.out.println("Boolean literal:"+b);
