Mastering Java 2026 – 400 Free Practice Questions to Pass the 'Thinking in Java' Exam

The 'this' keyword in Java refers to the current class instance. This is often used to refer to the fields and methods of the current object. Option B is incorrect because the superclass instance is accessed using the 'super' keyword. Option C is incorrect because static methods do not have an associated object and therefore cannot use 'this'. Option D is incorrect because siblings are objects that are created from the same class, but they represent different instances, so 'this' would not refer to a sibling instance.
