Sum Two Integers Value using Java

In my last tutorial entitle “Printing Hello Word in Java”, discuss the structure of Java programs and its parts.

This tutorial will teach you on how you can sum two integers values using Java. Integer is one of the examples of Data type in Java.

Remember that there are many Data type that handles Number values and Integer can only handle whole numbers.

Sum Two Integer Value in Java steps

1.Create a new project in Netbeans and name the project on what you want to name it.

2.Insert a main method inside your Class.

[java]public static void main(String args[]){

}[/java]

3.Declare three integer variables and initialized it inside your new created main method.

[java]int num1=2;
int num2=2;
int total=0;[/java]

3.Insert the code below to calculate and display the result.

[java]total = num1 + num2;
System.out.println("The sum is :" + total);[/java]

4. Run your program and the result should look like the image below.

5. Complete source code

[java]public class SumTwoIntegers {
public static void main(String args[]){
int num1=2;
int num2=2;
int total=0;
total = num1 + num2;
System.out.println("The sum is :" + total);
}
}[/java]

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.
