Hello, I need quick help with Java

1) Run the command below in a terminal to display the version of java installed on your computer?

2) List the result of running this command. Command: java -version

3) Download the SimpleCalculator.java file, compile and run it from the command line. List all the commands you use. Is the SimpleCalculator.java file called source code or byte code?

4) Check to see that a file named SimpleCalculator.class is created in the SimpleCalculator.java directory. Explain what this file is.

5) List computer hardware components that are involved to run the program.

6) What does SimpleCalculator.java do?

7) Make an intentional syntax error (also called compile error). Describe the error you made and list the error message.

8) Make an intentional runtime error (also called logic error). Describe the error you made and explain why it is a logical error.

// Modulus int mod = numD % numE; System.out.println(" =========="); System.out.println(" A % B = " + mod); System.out.println("=========="); } }
