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

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

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.

  • //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
