Java String is a very important topic in Java. It’s basically an object, that represent sequence of char values. Also, you can create String objects by using the new keyword and a constructor.

char[] ch={‘r’,’o’,’a’,’d’,’t’,’o’,’s’,’d’,’e’,’t’};
String string=new String(ch);

is same as

String string=”roadtosdet”;

Example 1:

public class Main {
    public static void main(String[] args) {
        char[] ch={'r','o','a','d','t','o','s','d','e','t'};
        String arrayString=new String(ch);
        System.out.println(arrayString);
        String string="roadtosdet";
        System.out.println(string);
    }

}

Example 2:

public class Main {
    public static void main(String[] args) {
        char[] ch={'r','o','a','d','t','o','s','d','e','t'};
        String arrayString=new String(ch); //creating character object
        System.out.println(arrayString);
        String string1="roadtosdet"; //assign string value to variable
        System.out.println(string1);
        String string2=new String(string1); //creating String object
        System.out.println(string2);
    }

}
