Using String constructor

String class in Java provides a constructor which accepts a character array, will create a string object, and stores the array of characters in it.

package stringPrograms;
public class ArrayToString {
  public static void main(String[] args) {
    char chars[] = {'c','o','d','e','d','a','i','l','y'}; //character array
    String str = new String(chars);
    System.out.println(str);
  }
}

Using StringBuilder class

StringBuilder class in Java can append character to it’s object. After appending all the characters can be converted to String object using toString() method.

public class ArrayToString {
  public static void main(String args[]) {
    // Defining character array
    char [] chars = {'c','o','d','e','d','a','i','l','y'};

    StringBuilder sb = new StringBuilder();

    //Using append() method to create a string
    for (int i = 0; i < chars.length; i++) {
      chars.append(a[i]);
    }
    System.out.println(sb.toString());
  }
}

Using valueOf() method of String class

This method takes the character array as input and converts the character array to a format where the entire value of the characters present in the array is displayed. In short, the array is converted to a String.

public class ArrayToString {
  public static void main(String args[]) {
    // Defining character array
    char [] chars = {'c','o','d','e','d','a','i','l','y'};
    // Using valueOf method to convert
    String str = String.valueOf(chars);
    System.out.println(str);
  }
}
