Java Output & Print – Tutorial 3 | GLO TECH
👋 Welcome back to GLO TECH! In today’s lesson, we will explore how to display text and numbers in Java using the println() and print() methods. Mastering output in Java is essential for writing interactive programs.
1️. Printing Text in Java
In Java, the System.out.println() method allows us to print text. Each statement moves to a new line automatically.
Example:
System.out.println("Hello World!");
System.out.println("I am learning Java.");
System.out.println("It is awesome!");
Each statement prints on a separate line, making the output clear and easy to read.
2️. Using Double Quotes
Text must always be enclosed in double quotes (""). Forgetting them will result in an error.
✅ Correct:
System.out.println("This sentence will work!");
❌ Incorrect:
System.out.println(This sentence will produce an error);
Always remember to wrap text in double quotes!
3️. The Difference Between print() and println()
The print() method is similar to println(), but it does not add a new line after printing.
Example:
System.out.print("Hello World! ");
System.out.print("I will print on the same line.");
📌 Tip: Adding an extra space in the first print() statement improves readability.
For simplicity, we will primarily use println() in this tutorial since it makes outputs easier to read.
4️. Printing Numbers in Java
Java also allows us to print numbers using println().
However, unlike text, numbers do not need double quotes:
Example:
System.out.println(3);
System.out.println(358);
System.out.println(50000);
5️. Performing Calculations in Print Statements
You can even perform mathematical operations inside println():
Example:
System.out.println(3 + 3); // Output: 6
System.out.println(2 * 5); // Output: 10
This feature is useful when working with dynamic calculations in your programs!
