Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Step 1: Declare the class, Step 2: Define the main method, Step 3: Add other members, Step 4: Write code in main, Step 5: Compile and run
First declare the class, then define the main method, add other members, write code in main, and finally compile and run.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Step 1: Declare the class, Step 2: Define the main method, Step 3: Add other members, Step 4: Write code in main, Step 5: Compile and run
Why this is correct
This is the correct order because you must first declare a class to contain the code, then define the main method as the entry point, optionally add other class members, write the executable code inside main, and finally compile and run the program.
- ✗
Step 1: Declare the class, Step 2: Add other members, Step 3: Define the main method, Step 4: Write code in main, Step 5: Compile and run
Why it's wrong here
This is incorrect because adding other members (e.g., fields or helper methods) before defining the main method is not invalid per se, but the logical order for a simple program is to first define the entry point. Doing it this way can cause confusion as the main method is not yet established.
- ✗
Step 1: Define the main method, Step 2: Declare the class, Step 3: Add other members, Step 4: Write code in main, Step 5: Compile and run
Why it's wrong here
This is incorrect because you cannot define a method without first having a class to contain it. In Java, all methods must be inside a class, so the class declaration must come first.
- ✗
Step 1: Declare the class, Step 2: Write code in main, Step 3: Define the main method, Step 4: Add other members, Step 5: Compile and run
Why it's wrong here
This is incorrect because you cannot write code inside a method before the method is defined. The method signature must be defined before writing its body.
