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 -

Method 1: Using toString() method

Program:

public class CharToString_toString
    {
      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);
      }
    }

Output:

String is: g

Method 2: Using valueOf() method

Program:
public class CharToString_valueOf 
    {
      public static void main(String[] args) 
      {
        char myChar = 'g';
        //valueOf method take character parameter and convert string.
        String myStr = String.valueOf(myChar);
        ////print string value
        System.out.println("String is: " + myStr);
      }
    }

Output:
String is: g

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

Program:
    //Convert String to Character using string method 
    public class StringToChar 
    {
    public static void main(String[] args) 
     {
      //input String 
           String myStr = "java100";
           //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: j
Character at 1 Position: a
Character at 2 Position: v
Character at 3 Position: a
Character at 4 Position: 1
Character at 5 Position: 0
Character at 6 Position: 0
