How to Convert Char to String & String to char in Java

In this tutorial, we will study programs to

1. To convert a character to String
2. To convert a String to character

Convert Char To String

There are multiple ways to convert a Char to String in Java. In fact, String is made of Character array in Java. Char is 16 bit or 2 bytes unsigned data type.

We can convert String to Character using 2 methods -

1. Method 1: Using toString() method
2. Method 2: Using valueOf() method

//Convert character to String using string method 
package com.guru99;
 
public class CharToString {
 
	public static void main(String[] args)
	{
 
		//input character variable 
		char myChar = 'g';
		
		//Using toString() method
		//toString method take character parameter and convert string.
		String myStr = Character.toString(myChar);
		
		//print string value
		System.out.println("String is: "+myStr);
 
		
		//we can use other method for valueOf()
		
 
		//valueOf method take character parameter and convert string.
		myStr = String.valueOf(myChar);
		////print string value
		System.out.println("String is: "+myStr);
 
	}
 
}

Output :

String is: g
String is: g

Convert String to char

We can convert a String to char using charAt() method of String class.

//Convert String to Character using string method 
package com.guru99;
 
public class StringToChar {
 
	public static void main(String[] args) 
	{
		//input String 
	      String myStr = "Guru99";
	      
	      //find string length using length method.
	      int stringLength =myStr.length();
	      
	      //for loop start 0 to total length
	      for(int i=0; i < stringLength;i++)
	      {
	    	  //chatAt method find Position and convert to character.  
	        char myChar = myStr.charAt(i);
	        
	        //print string to character
	        System.out.println("Character at "+i+" Position: "+myChar);
	      }
 
	}
 
}

Output:

Character at 0 Position: G
Character at 1 Position: u
Character at 2 Position: r
Character at 3 Position: u
Character at 4 Position: 9
Character at 5 Position: 9
