Which of the following is true about the `this` keyword in Java?

The this keyword in Java serves a specific purpose: it refers to the current object instance on which a method or a constructor is invoked. This is crucial for distinguishing between instance variables and parameters with the same name, enabling developers to access the object’s attributes and methods effectively.

For instance, consider a class with a constructor that takes parameters. By utilizing this, the code can differentiate between the instance variables and the constructor parameters. This distinction is essential for maintaining clear and functional code, as it clarifies which variables are being affected or referenced during execution.

In contrast, using this in a static context is not permissible, as static methods belong to the class rather than any specific object instance. Inner classes can indeed use this, but in a different context (they refer to the instance of the inner class, not the outer class). Additionally, this does not refer to the most recent object created; rather, it always points to the specific instance for which a method or constructor is currently executing. This behavior is fundamental to Java's object-oriented programming model, enabling encapsulation and organization of code.
