Answer 1

Problem

As your named your own class String , it hides the built-in class java.lang.String

String s = "Anik";
^^^^^^     ^^^^^^
|          | built-in java.lang.String
|
your class FirstJava.String

---

Solution

Never name a class, a variable, whatever like an existing stuff, of your own or built-in

Answer 2

The String is not a reserved keyword it's a predefined non-primitive datatype in java that comes under package java.lang.String(class) that is by default imported in a java program. Also you should not use names/identifiers that have already being used as we see in case of String.

public class String {
public static void main(java.lang.String[] args) {
  java.lang.String string = "Anik";
  System.out.println(string);
  }
}
