Select the correct answer
Which of the following modifiers can be used to disallow a method from being overridden?
Options
transient
final
volatile
static
Solution
Break Down the Problem
- Identify the purpose of each modifier listed in the options: transient, final, volatile, and static.
- Determine which of these modifiers prevents a method from being overridden.
Relevant Concepts
- final: In Java, a method declared as
final
cannot be overridden by subclasses. - transient: This modifier is used to indicate that a field should not be serialized.
- volatile: This modifier ensures that a variable's value is always read from and written to the main memory, not from thread-local storage.
- static: This modifier indicates that a method belongs to the class, rather than instances of the class, allowing it to be called without creating an instance.
Analysis and Detail
- The
final
modifier explicitly prevents subclasses from modifying the behavior of the method. - The other modifiers (transient, volatile, static) serve different purposes that do not involve method overriding.
Verify and Summarize
The final
keyword is specifically designed to prevent any further modifications or overriding of the method by any class that extends the class containing the method.
Final Answer
final is the correct answer as it disallows a method from being overridden.
