Answer 2

Answer:

a, c are true

Explanation:

1. Instance methods provide direct access to instance variables and methods.
2. Class variables and class methods are readily accessible through instance methods.
3. Class variables and class methods are immediately accessible via class methods.

• I've learned from reading the Java documentation that a field declared with the "static" keyword is a class variable (or static field), and that a method defined with the "static" keyword is a static method (or class method). The class name itself serves as a reference for class variables and class methods.
• To execute an instance method, we must first construct an object of the class in which it is defined. Instance methods are methods that need the creation of an object of their class in order to be called.
• A class's instance variables are declared outside of any blocks, methods, or constructors.
