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
