In how many ways we can convert a String to a character array using Java?

You can convert a String to a character array either by copying each element of the String to an array or, using the toCharArray() method.

Copying each element

• Get the String to be converted.

• Create an empty character array with the length of the String.

• The charAt() method of the String class returns the character at a particular position. Using this method copy each character of the String to the array.

Example

 Live Demo

import java.util.Arrays; import java.util.Scanner; public class StringToCharArray {    public static void main(String args[]) {       Scanner sc = new Scanner(System.in);       System.out.println("Enter a String value: ");       String str = sc.next();       //Creating an empty array with the length of the String       char chArray[] = new char[str.length()];       //Copying each element of the String to the array       for(int i=0; i<str.length(); i++) {          chArray[i] = str.charAt(i);       }       System.out.println("Contents of the character array: ");       System.out.println(Arrays.toString(chArray));    } }

Output

Enter a String value: Tutorialspoint Contents of the String array: [T, u, t, o, r, i, a, l, s, p, o, i, n, t]

Using toCharArray() method

The toCharArray() method of the Strong class converts the current String into a character array and returns it. Therefore, to convert a Sting into a character array using this method −

• Get the String to be converted.

• Create an empty character array with the length of the String.

• Convert the String to character array using the toCharArray() method and store it in the above created empty array.

Example

 Live Demo

import java.util.Arrays; import java.util.Scanner; public class ToCharArrayExample {    public static void main(String args[]) {       Scanner sc = new Scanner(System.in);       System.out.println("Enter a String value: ");       String str = sc.next();       //Creating an empty array with the length of the String       char chArray[] = str.toCharArray();       System.out.println("Contents of the character array: ");       System.out.println(Arrays.toString(chArray));    } }

Output

Enter a String value: Tutorialspoint Contents of the character array: [T, u, t, o, r, i, a, l, s, p, o, i, n, t]
