Final answer:
The 'this()' keyword cannot be called from just anywhere in an instance method. It must be used exclusively as the first statement in a constructor to call another constructor within the same class, thus the statement is false. Option 2 is correct.
Step-by-step explanation:
The question pertains to the use of the this() keyword in instance methods within object-oriented programming. In Java, the this() call is used specifically to invoke other constructors within the same class, and it follows strict rules for usage. It must be the first statement in a constructor, so it cannot be called from just 'anywhere' in an instance method.
If you attempt to use this() from an arbitrary point within an instance method, you will encounter a compile-time error. Therefore, the answer to the question is False, this() cannot be called from anywhere in an instance method. You can only use this() within a constructor as the first statement to call another constructor in the same class.
The this() keyword is used in Java to call the constructor of the same class. However, it cannot be called from anywhere in an instance method. The this() keyword can only be used inside a constructor and it must be the first statement in the constructor. It is used to invoke another constructor in the same class.
