Question 3

What series of System.out.print and System.out.println statements would produce the following output?

Several slashes are sometimes seen,
said Sally. I've said so. See?

Make sure to choose all options that produce the desired output.

Hint: For each print and println statement, track where your cursor is going to be at the end of that statement!

1.  System.out.print("Several slashes are sometimes seen,");
    System.out.print("said Sally. I've said so. See?");
   

2.  System.out.println("Several slashes are sometimes seen,");
    System.out.println("said Sally. I've said so. See?");
   

3.  System.out.print("Several slashes ");
    System.out.print("are sometimes seen,");
    System.out.println("said Sally. I've said so. See?");
   

4.  System.out.print("Several slashes ");
    System.out.println("are sometimes seen,");
    System.out.println("said Sally. I've said so. See?");
   

See Answer

Options 2 and 3 are correct!

Question 4 What is the output of the following series of System.out.print and System.out.println statements:

System.out.print("There's one thing every coder ");
System.out.println("must understand:");
System.out.println("The System.out.println command.");

Write it as you would see on the terminal. (i.e. no quotation marks!)

See Answer

There’s one thing every coder must understand: The System.out.println command.

Explanation

First, we print out There's one thing every coder but stay on the same line since it is just a print statement. Then, we print out must understand: on the same line and then move to the next line because it is a println statement. Finally, we print out The System.out.println command. and move to the next line.

Answer:

There's one thing every coder must understand:
The System.out.println command.
