Is delete, next, main, exit or null keyword in java?
In Java, the terms you mentioned are not keywords. Here's a breakdown of each:
delete: This is not a keyword in Java. In some other programming languages (like C++), delete is used to deallocate memory, but Java has automatic garbage collection, so memory management is handled differently.
next: This is not a keyword in Java. However, it is commonly used as a method name in classes like Scanner (e.g., nextInt(), nextLine()) to read input.
main: This is not a keyword, but it is a special method name in Java. The main method is the entry point of any standalone Java application. It is defined as public static void main(String[] args).
exit: This is not a keyword in Java. However, System.exit(int status) is a method used to terminate the Java Virtual Machine (JVM).
null: This is a literal in Java, representing a null reference, which means that a variable does not point to any object.
In summary, among the terms you listed, only null is a literal, while main is a special method name, and the others are neither keywords nor literals in Java.
