Character Datatype Example in Java

Introduction

Character Datatype is a classic Java console program that demonstrates the concept with complete source code and sample output. Java primitive types and wrappers behave differently from objects — these examples show declaration, range and conversion.

This tutorial walks through the program line by line, explains how the logic works, and highlights best practices you can apply in your own code.

Definition

The char data type is a single 16-bit Unicode character. It has a minimum value of ‘\u0000’ (or 0) and a maximum value of ‘\uffff’ (or 65,535 inclusive).

Syntax

char varibale_name = 'any_single_charecter';

Syntax Example

char gear = 'A';

Character Datatype Example Program

class CharacterDatatype{
	public static void main(String[] args){
		char c='m';
		System.out.println("The character is: "+c);
	}
}

Sample Output

The character is: m

When to use

Use this character datatype example when learning or revising core Java syntax.

How it works

1. Execution begins in the main method — the JVM calls this method when you run the class.

2. char c='m'; updates a variable used in the calculation or output.

3. A println / print call writes text to the console — part of the sample output below.

4. Compare your console output with the sample output for Character Datatype to confirm the program behaves correctly.
