SHARE:

A quick guide on how to convert char to string in java in different ways.

1. Overview

In this tutorial, We'll learn how to convert char to string in java using Character.toString(), String.valueOf() and + operator with empty string.
Java - How to Convert Char To String?


2. Java Char to String Using Character.toString()


Character.toString(char) method takes the character as argument returns the same character as String format.

Character.toString() method returns a String with length or size exactly 1.

This method is available in java 1.4 onwards.

The below example is converting char to string java.
package com.javaprogramto.convert.chartostring;

/**
 * example to convert char to string in java using Character.toString() method.
 * 
 * @author javaprogramto.com
 *
 */
public class CharToStringExample1 {

	public static void main(String[] args) {

		// example 1

		char ch = 'c';

		String strC = Character.toString(ch);
		System.out.println("Example 1: ");
		System.out.println("Char in String : " + strC);
		System.out.println("returned string length : " + strC.length());

		// example 2

		char ch2 = 'z';

		String strZ = Character.toString(ch2);

		System.out.println("\nExample 2: ");
		System.out.println("Char in String : " + strZ);
		System.out.println("returned string length : " + strZ.length());

	}

}

Output:
Example 1: 
Char in String : c
returned string length : 1

Example 2: 
Char in String : z
returned string length : 1


3. Java Char to String Using String.valueOf(char)


String.valueOf() method takes the char as a parameter and returns a String with the char value.

valueOf() method always returns the string representation of char value and its length will be always 1.

Example:
package com.javaprogramto.convert.chartostring;

/**
 * example to convert char to string in java using String.valueOf() method.
 * 
 * @author javaprogramto.com
 *
 */
public class CharToStringExample2 {

	public static void main(String[] args) {

		// example 1
		char ch3 = 'x';

		String strC = String.valueOf(ch3);
		System.out.println("String.valueOf Example 1: ");
		System.out.println("Char in String : " + strC);
		System.out.println("returned string length : " + strC.length());

		// example 2
		char ch4 = '7';

		String strZ = String.valueOf(ch4);

		System.out.println("\nString.valueOf Example 2: ");
		System.out.println("Char in String : " + strZ);
		System.out.println("returned string length : " + strZ.length());

	}

}
Output:
String.valueOf Example 1: 
Char in String : x
returned string length : 1

String.valueOf Example 2: 
Char in String : 7
returned string length : 1

4. Java Char to String Using + operator with an empty string


You can use the + operator to add the char to the string which is empty.

+ operator can be used in the string concatenations.

First create the empty string literal "" and add the character to the string using + operator as below. This step will return the new string with only the character.
package com.javaprogramto.convert.chartostring;

/**
 * char to string using + operator
 * 
 * @author javaprogramto.com
 *
 */
public class CharToStringExample3 {

	public static void main(String[] args) {

		char ch3 = 'x';
		String returnedString = "" + ch3;
		System.out.println("Returned string 1 : " + returnedString);

		char ch1 = 'a';
		String returnedString2 = "" + ch1;
		System.out.println("Returned string 2 : " + returnedString2);

		char ch2 = 'b';
		String returnedString3 = "" + ch2;
		System.out.println("Returned string 3 : " + returnedString3);
	}
}

Output:
Returned string 1 : x
Returned string 2 : a
Returned string 3 : b
