✅ How to Display Text with printf in Java

Basic Syntax

System.out.printf(formatString, arguments);

  • formatString contains text with format specifiers.

  • arguments are values you want to insert into the text.

Common Format Specifiers

Specifier Meaning Example
%s String "Hello %s"
%d Integer "Number: %d"
%f Floating-point number "Price: %.2f"
%n New line (platform independent)

🔢 Example: Display formatted text

public class PrintfExample
{
public static void main(String[] args)
 {
  String name = "Alice";
  int age = 30;
  double salary = 12345.6789;
  System.out.printf("Name: %s%n", name);
  System.out.printf("Age: %d years%n", age);
  System.out.printf("Salary: $%.2f%n", salary);
 }
}

🟢 Output

Name: Alice
Age: 30 years
Salary: $12345.68

Tips:

  • %n is better than \n because it works across OSes.

  • Use %.2f to show 2 decimal places for floats/doubles.
