Introduction

In Java, to standard output (screen) you can simply use:

• System.out.println();
• System.out.print();
• System.out.printf();

Here:

• System is a class
• out is a public static field

println() and print()

• print() - It prints string inside the quotes.
• println() - It prints string inside the quotes similar like print() method. Then the cursor moves to the beginning of the next line.

class Output {
    public static void main(String[] args) {
    	
        System.out.println("1. println ");
        System.out.println("2. println ");
    	System.out.println();
    	
        System.out.print("1. print ");
        System.out.print("2. print");
    }
}

Output:

1. println 
2. println 
 
1. print 2. print

It can be used to print variables:

int x = 5;
int y = 6;
System.out.println(x + y); // Print the value of x + y
 
 
String firstName = "John ";
String lastName = "Doe";
String fullName = firstName + lastName;
System.out.println(fullName);

printf()

Similar to f string.

String name = "John";
int age = 30;
 
System.out.printf("Hello, my name is %s and I am %d years old.", name, age);
