Question

Consider the following statement written in class Student where school_Name is its data member.

static final String school_Name = "Co-Ed School";

Which of the following statements are valid for school_Name?

1. All objects of class Student share the same value of school_Name.
2. The value of school_Name cannot be changed during program execution.
3. The keywords static and final cannot be used together for a variable.

Options

• Only I and II

• Only II and III

• Only I and III

• Only III

Answer 1

Only I and II

Explanation:

Here is the breakdown of why those lines are correct for the Java statement static final String school_Name = "Co-Ed School";:

• Line I is Correct (static): Because the variable is static, it is stored in the class memory rather than inside each individual object. This means every "Student" object shares this exact same school name.
• Line II is Correct (final): Because the variable is final, it acts as a constant. Once it is set to "Co-Ed School", the program will not allow you to change it to something else later.
• Line III is Incorrect: It is a standard practice in Java to use static and final together to create constants. There is no rule preventing them from being used on the same variable.
