Java SE 8 Programmer I — Question 103

Which three statements are true about the structure of a Java class? (Choose three.)

Answer options

• A. A class cannot have the same name as its field.
• B. A public class must have a main method.
• C. A class can have final static methods.
• D. A class can have overloaded private constructors.
• E. Fields need to be initialized before use.
• F. Methods and fields are optional components of a class.

Correct answer: C, D, F

Explanation

Option C is correct as Java classes can indeed have final static methods. Option D is also correct because a class can have multiple private constructors with different parameters. Option F is correct since methods and fields are optional, meaning a class can exist without them. Options A, B, and E are incorrect because a class can have the same name as its field, a public class does not need a main method, and fields do not necessarily need to be initialized before use.
