Introduction to Java Programming

What is the role of an IDE in Java programming?

• To provide a development environment with tools for writing and debugging code

• To run the code

• To compile the code

• To convert Java code to machine language

What is the purpose of the 'public' keyword in a class declaration?

• To start the main method

• To make the class accessible to other classes

• To declare a variable

• To define a private class

Which of the following is true about the main method in Java?

• It is optional in a Java program

• It can have multiple instances in a program

• It must be named 'main' with a lowercase 'm'

• It does not require any keywords before its declaration

What is the purpose of comments in Java code?

• To print messages to the console

• To execute additional code

• To provide information to the programmer

• To declare variables

Which symbol is used to start a block comment in Java?

• //

• /*

• */

• #

What happens if you violate a syntax rule in Java?

• The program will run with warnings

• The program will run but with incorrect output

• The program will not compile and will show a compiler error

• The program will ignore the error and continue

What is a runtime error in Java?

• An error that occurs when the program is running

• An error that occurs due to incorrect syntax

• An error that occurs during the compilation of the program

• An error that occurs due to missing semicolons

What is the difference between 'print' and 'println' methods in Java?

• 'println' prints the message without moving the cursor

• 'println' prints the message and then moves the cursor to the next line

• 'print' prints the message and then moves the cursor to the next line

• 'print' moves the cursor to the next line after printing

Why is good coding style important in Java?

• To make the code easier to read and understand

• To reduce the size of the code

• To avoid runtime errors

• To make the code run faster

Which style is usually modeled after in the computer science exam?

• End of Line style

• Inline style

• Next Line style

• Block style
