Output using System.out.print in Java - Mini Project: Build & Apply

Output using System.out.print

📖 Scenario: You are creating a simple Java program to display messages on the screen. This is like writing a note on a board for your friends to read.

🎯 Goal: Learn how to use System.out.print to show text on the screen without moving to a new line.

📋 What You'll Learn

Create a string variable called message with the exact text "Hello, friend!"

Create an integer variable called number with the exact value 5

Use System.out.print to display the message variable

Use System.out.print to display the number variable immediately after the message

💡 Why This Matters

🌍 Real World

Displaying messages and information on the screen is a basic need in many programs, like showing scores in games or instructions in apps.

💼 Career

Knowing how to output information is essential for debugging and user interaction in software development.

1

Create variables for message and number

Create a string variable called message and set it to "Hello, friend!". Then create an integer variable called number and set it to 5.

Java

// Create a string variable called message with value "Hello, friend!"
// Create an integer variable called number with value 5
// Your code here

Need a hint?

Use String message = "Hello, friend!"; and int number = 5; inside the main method.

2

Use System.out.print to show the message

Use System.out.print to display the variable message.

Java

public class Main {
    public static void main(String[] args) {
        String message = "Hello, friend!";
        int number = 5;
        // Use System.out.print to display message
        // Your code here
    }
}

Need a hint?

Write System.out.print(message); inside the main method.

3

Use System.out.print to show the number after the message

Use System.out.print to display the variable number immediately after the message.

Java

public class Main {
    public static void main(String[] args) {
        String message = "Hello, friend!";
        int number = 5;
        System.out.print(message);
        // Use System.out.print to display number
        // Your code here
    }
}

Need a hint?

Write System.out.print(number); right after printing the message.

4

Display the combined output

Run the program and print the combined output of message and number using System.out.print statements.

Java

public class Main {
    public static void main(String[] args) {
        String message = "Hello, friend!";
        int number = 5;
        System.out.print(message);
        System.out.print(number);
        // No extra code needed here
    }
}

Need a hint?

When you run the program, it should show Hello, friend!5 without moving to a new line.
