How to convert a char array back to a string?

To convert a char array back to a String in Java, you can use the String class's constructor that takes a char array as an argument.

Here's an example of how you can convert a char array to a String:

public class Main {
  public static void main(String[] args) {
    char[] charArray = {'h', 'e', 'l', 'l', 'o'};
    String str = new String(charArray);
    System.out.println(str); // prints "hello"
  }
}

In this example, the char array is passed to the String constructor, which creates a new String object with the same characters as the char array.

You can also use the String.valueOf() method to convert a char array to a String. For example:

public class Main {
  public static void main(String[] args) {
    char[] charArray = {'h', 'e', 'l', 'l', 'o'};
    String str = String.valueOf(charArray);
    System.out.println(str); // prints "hello"
  }
}

I hope this helps! Let me know if you have any questions.
