Solution

In Java, this() and super() are special keywords that represent the current instance of a class and the parent class respectively. They are primarily used in constructors, not in methods.

  1. this(): It is used to call the default constructor of the current class. It must be the first statement in the constructor. It is primarily used for constructor chaining, where one constructor calls another constructor.

  2. super(): It is used to call the default constructor of the parent class. Like this(), it must be the first statement in the constructor. It is used when we want to access/call the parent class's constructor.

If you try to use this() or super() in a method, it will result in a compile-time error. They can only be used inside constructors.

However, this and super (without parentheses) can be used in methods.

  1. this: It can be used to refer to the current class's instance variable.

  2. super: It can be used to refer to the parent class's variable or method.

So, if this() or super() are used in a method, it would not be valid and would result in a compile-time error.
