Which of the following is true for static final fields in Java?

  1. They are considered global variables

  2. They can be modified using reflection

  3. They are compile-time constants

  4. They are initialized at runtime

The correct answer is: They can be modified using reflection

Static final fields in Java are considered global variables, meaning they can be accessed and used in any part of the code. However, option B is incorrect because static final fields cannot be modified using reflection. Reflection is a feature in Java that allows code to inspect and modify itself at runtime, but static final fields cannot be modified once they are initialized, which leads to option C being incorrect. Static final fields are also not initialized at runtime. In fact, they are initialized at compile-time, making option D incorrect. The correct answer, option B, states that static final fields are compile-time constants. This means that they cannot be reassigned or altered after compilation, making them constant values throughout the program. This makes them useful for storing values that should not be changed, such as mathematical constants or configurations.
