This tutorial entitles “Number Pattern 1 using Loop in Java” will teach you on how you can display a number pattern forming a triangle using for loop. Please follow all the steps to complete this tutorial.
Looping is a common feature use in any programming language especially in Java Program. This is a repetition statement with condition. If the condition is meet, the repetition or the looping stop.
There are three types of loop, the while loop, do while loop, and for loop.
Number Pattern 1 using Loop in Java Steps
- Create a new class and name it what you want to name.

2. Create a main method inside your class.
[java]public static void main(String args[]){
}[/java]3. Insert the code below inside your main method for looping.
[java]for (int i = 1; i <=5;i++){
for (int j = 1;j <= i;j++){
System.out.print(j);
}
System.out.println();
}[/java]Remember: 1 start the looping and 5 end the looping.
4. Run your program and the output should look like the image below.

5. Complete Source Code
[java]public class PatternNumber1 {
public static void main(String args[]){
for (int i = 1; i <=5;i++){
for (int j = 1;j <= i;j++){
System.out.print(j);
}
System.out.println();
}
}

Frequently Asked Questions
How does this Java project work?
Built with Java Swing (NetBeans IDE) and MySQL backend via JDBC. Standard structure: JFrame designer to event handlers to DAO layer to MySQL. Login form for auth. Ready to extend for BSIT capstone scope.
What Java JDK and MySQL versions does this project require?
Most projects in this batch use Java JDK 8 or 11 with MySQL 5.7+ or MariaDB 10+. To run: install JDK (Adoptium / Oracle), install MySQL Server + MySQL Workbench, install NetBeans IDE (15+ supports modern JDK), open the project (.zip extracted folder), right-click + Open Project, add MySQL JDBC driver to Project Libraries, run.
How do I set up the database for this Java project?
Open MySQL Workbench (or phpMyAdmin if you have XAMPP), create a new empty database with the name specified in the project. Import the included .sql file via Server, Data Import in Workbench (or Import tab in phpMyAdmin). Update the connection class (usually DBConnection.java or DatabaseConnection.java) with your MySQL host, port, username, password, and database name.
Can I use this Java project for a BSIT capstone or thesis?
Yes, Java is one of the most accepted languages by Philippine BSIT panels. Extend it: add role-based access (admin/staff/customer login redirect), JasperReports printable reports, dashboards with JFreeChart, audit log, multi-branch support. Pair with Chapter 1-5 documentation matching your panel’s rubric.
Why am I getting ‘ClassNotFoundException: com.mysql.jdbc.Driver’ or ‘No suitable driver’?
Three common Java JDBC issues: (1) MySQL JDBC driver JAR not added to project Libraries. Right-click Project, Properties, Libraries, Add JAR/Folder, select mysql-connector-java-X.X.X.jar. (2) Wrong driver class name. Modern (8.0+) uses com.mysql.cj.jdbc.Driver, legacy (5.x) uses com.mysql.jdbc.Driver. (3) Connection URL missing serverTimezone parameter, add ?serverTimezone=UTC to the URL.
Where can I find more Java projects with source code?
Browse the Java Projects hub for the full library (120+ Java desktop systems). For modern Java web alternatives consider Spring Boot. For other desktop stacks see VB.NET Projects or C# Projects. For BSIT capstone idea lists see 150 Best Capstone Project Ideas.
