Program to convert String to char & char array in java

• Given String value in java.
• We would like to convert String to char & char array using following methods.
  • charAt method of String class returns character of String at specified index.
  • toCharArray method of String class converts String to new character array

Example:  convert String to char & char array in java

Example : Given inputString = "Java"

//character at specified Index
char at 0 index = 'J'
char at 1 index = 'a'
char at 2 index = 'v'
char at 3 index = 'a'
//Convert String to character array:
Character array would be like = [J, a, v, a]

Java methods of String class to convert String to char & char array

Program: Convert string to char & character array in java

package org.learn;

import java.util.Arrays;

public class ConvertStringToCharAndArray {

    public static void main(String[] args) {

        String strValue = "Java";

        System.out.println("Input String : " + strValue);

        //Convert char to string using Character.toString
        System.out.println("Char at zero index : "+ strValue.charAt(0));
        System.out.println("Char at 1 index : "+ strValue.charAt(1));
        System.out.println("Char at 2 index : "+ strValue.charAt(2));
        System.out.println("Char at 3 index : "+ strValue.charAt(3));

        System.out.print("Print all characters using loop : ");
        //Loop through string & print all characters
        for(int index = 0; index < strValue.length(); index++) {
            System.out.print(strValue.charAt(index));
        }

        //Convert String to char array
        char chArray[] = strValue.toCharArray();

        System.out.println("\nString to Character array :"+
                Arrays.toString(chArray));
    }
}

Output: convert String to char & character array in java

Input String : Java
Char at zero index : J
Char at 1 index : a
Char at 2 index : v
Char at 3 index : a
Print all characters using loop : Java
String to Character array :[J, a, v, a]
