When programming, it is useful to print information to the terminal screen/console output window.
Here is a basic example of printing to the screen:
System.out.println("Hello World!"); // prints Hello World! on its own line
System part of the statement accesses all of the methods/classes associated with the
out part accesses all of the methods/classes related to output.
println is a method contained in
System.out. It is abbreviated and stands for "Print Line," or "print the following information and then a new line."
The new line comes from outputing a
\n, or newline character, which is like pressing enter on your keyboard. You can use the
System.out.print method if you do not want to print a newline character by default, like this:
System.out.print("Hello World!"); // prints Hello World! on the line
You might use a print statement if your program takes an integer
dollarAmount from the user, then prints the final amount with sales tax / meals tax to the screen.
