Java – Convert string to char array

To convert a string to char array in Java, you can use String.toCharArray() method. Call the toCharArray() method on the given string, and the method returns a char array created from the characters of the string.

In this tutorial, we will learn how to use a convert a given string to an array of characters in Java, with examples.

1. Convert string “HelloWorld” to char array in Java

In this program, we shall take a string "Hello World" in variable str, convert this string to a char array characters, and then print them to output using a For loop.

Java Program

public class Main {
	public static void main(String[] args) {
		String str = "HelloWorld";
        
		// Convert string to char array
		char[] characters = str.toCharArray();
        
		// Print the array
		for(var i=0; i<characters.length; i++) {
			System.out.println("characters["+ i +"] - " + characters[i]);
		}
	}
}

Output

characters[0] - H
characters[1] - e
characters[2] - l
characters[3] - l
characters[4] - o
characters[5] - W
characters[6] - o
characters[7] - r
characters[8] - l
characters[9] - d

Conclusion

In this Java String tutorial, we have seen how to convert a given string into an array of characters using String.toCharArray() method, with examples.
