    Think of the task logically. A string is an array of characters - so the string
    "Hello" has 4 characters (starting at zero) and ends with a NULL terminating character.

    H[0]
    E[1]
    ...etc

    import java.util.*;
    public class cArray{
      public static void main(String[]args){
       Scanner input = new Scanner(System.in);
     
        System.out.println("Please Give A String");
        String s1 = input.nextLine();
        char[]data = s1.toCharArray();
      }
    }

    I am converting a String into a Char Array in this way. Now I want to do the same thing without using toCharArray(). so I want to know the alternative way.

    In java strings are not terminated by a termination character. Thats in C++, C, etc.

    Read the string API and try for yourself. There are plenty of ways for doing this.

    Please don't post multiple threads on the same topic. Your other thread was deleted.

    As for your question, we will not write the code or do Internet searching for you. Review the String API for methods that you could use to do what you've described. Try writing the code, and if you run into problems or need help, post the code and ask specific questions about the help you need.

    As you are a beginner, these are basic skills you need to learn and practice.

    Have you tried to break the string into it's individual characters? As I said previously, a
    string is an array of characters. Think about different ways to do this example: repetition.
    When you have each character of the string, you can then work an algorithm to store the
    character into it's own array.
