Formatting Output

Part of the Fundamentals section of Coddy's Java journey. Lesson 34 of 73.

As of now, we learned how to print simple strings, but sometimes we need to insert variable values into the string.

For example:

int age = 10;
System.out.println("His age is: age");

This will print "His age is: age" instead of "His age is: 10"

To make it work, we will use formatted printing printf:

int age = 30;
String name = "Alice";
double balance = 1500.75;

System.out.printf("Name: %s, Age: %d, Balance: %.2f\n", name, age, balance);

%s is a placeholder for strings.
%d is a placeholder for integers.
%f is a placeholder for floating-point numbers.
%.2f formats the floating-point number to two decimal places.
\n is an escape sequence that moves the output to a new line.

Another way to combine strings with variables is with the plus + operator:

System.out.print("Name: " + name + " Age: " +  age + " Balance: " + balance);

Challenge

Beginner

You are given a code that stores a random string as input to a variable named rnd.

Print to the console "The input is: " and the random string that is inside the variable rnd.

Check the test cases for examples!

Try it yourself

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        String rnd = scanner.nextLine();
        
        // Write your code below
        
        scanner.close();
    }
}
