Creating a Thread with a Runnable target — which class definitions compile for "new Thread(target)"? Given: Runnable target = new MyRunnable(); Thread myThread = new Thread(target); Choose the valid implementation for MyRunnable.

Introduction / Context:To construct a Thread with a Runnable target, the argument must implement the java.lang.Runnable interface. The interface declares one method: public void run().

Given Data / Assumptions:

• The Thread constructor used is Thread(Runnable target).
• We are deciding which candidate MyRunnable compiles and can be passed to that constructor.

Concept / Approach:A class can implement an interface, not extend it. When implementing Runnable, the run method must be declared public to satisfy the interface’s public abstract signature. A package-private run() fails to implement the interface method due to reduced visibility.

Step-by-Step Solution:

Verification / Alternative check:Compile Option C and pass new MyRunnable() into new Thread(target); code compiles and runs.

Why Other Options Are Wrong:

• They either misuse inheritance for an interface or fail the visibility requirement.

Common Pitfalls:Forgetting that interface methods are implicitly public and must be implemented with public visibility.

Final Answer:public class MyRunnable implements Runnable{public void run(){}}
