In Java how to convert String to Char Array? (Two ways) – String() to Char[]

The simplest way to convert String to Char Array. How to convert String to Char Array in Java?

There are two different ways to covert String() to Char[] in Java:

1. Using string.toCharArray() Method
2. Using standard approach. Iterate through String and add to chat Array.

Here is a Java code:

Create Java class CrunchifyStringToCharArray.java. Put below code into a file.

package crunchify.com.tutorials;

/**
 * @author Crunchify.com
 * In Java how to convert String to Char Array? (Two ways) - String() to Char[]
 */

public class CrunchifyStringToCharArray {

    public static void main(String[] args) {

        // Method-1: using string.toCharArray()
        String crunchifyString = "This is Crunchify";
        // toCharArray() converts this string to a new character array.
        char[] crunchifyCharArray = crunchifyString.toCharArray();

        crunchifyPrint("=========== Method-1: using string.toCharArray()");
        for (char crunchifyResult1 : crunchifyCharArray) {
            crunchifyPrint(crunchifyResult1 + "");
        }

        // Method-2: Iterate through the string to copy character
        String crunchifyString2 = "Crunchify.com";
        crunchifyPrint("\n=========== Method-2: Standard way: Iterate through the String to copy character");
        char[] crunchifyCharArray2 = new char[crunchifyString2.length()];

        for (int counter = 0; counter < crunchifyString2.length(); counter++) {
            // charAt() returns the char value at the specified index. An index ranges from 0 to length() - 1.
            crunchifyCharArray2[counter] = crunchifyString2.charAt(counter);
        }

        for (char newCh : crunchifyCharArray2) {
            crunchifyPrint(newCh + "");
        }
    }

    private static void crunchifyPrint(String string) {
        System.out.println(string);
    }
}
