Java - How to Convert Char To String?

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.

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
