8) ¿QUÉ ES EL OUTPUT EN JAVA?

Java Output

You can simply use System.out.println(), System.out.print() or System.out.printf() to send output to standard output (screen).

System is a class and out is a public static field which accepts output data. Don't worry if you don't understand it. Classes, public, and static will be discussed in later chapters.

Let's take an example to output a line.

class AssignmentOperator {
    public static void main(String[] args) {
    	
    	System.out.println("Java programming is interesting.");   
    }
}

When you run the program, the output will be:

Java programming is interesting.

Here, println is a method that displays the string inside quotes.

What's the difference between println(), print() and printf()?

• print() - prints string inside the quotes.
• println() - prints string inside the quotes similar like print() method. Then the cursor moves to the beginning of the next line.
• printf() - it provides string formatting (similar to printf in C/C++ programming).
