Java Output

You print text to the screen with the System.out object. There are three main methods:

• print() prints text without moving to a new line.
• println() prints text and then moves to a new line.
• printf() prints formatted text using placeholders.

println

java

### System.out.println("Hello");

### System.out.println("World");

Output:

### Hello

### World

print

java

### System.out.print("Hello ");

### System.out.print("World");

Output (both stay on the same line):

### Hello World

Printing numbers

You can print numbers directly, without quotes:

java

### System.out.println(3);

### System.out.println(358);

### System.out.println(3 + 3);

printf with placeholders

java
int age = 25;

### System.out.printf("I am %d years old", age);

Here %d is a placeholder for a number.

TL;DR

• println() adds a new line after the text.
• print() stays on the same line.
• Numbers are printed without quotes.
• printf() uses placeholders for formatted output.
