Java Programs Page

Syntax

public static void main(String[] args) {
   //Program code goes here
}

Example

Create a program that calculates the sum of two numbers and outputs the result.

Output

The output of the program should be the sum of the two numbers.

Explanation

Java programs typically begin with the main() method, which is the entry point for the program. This method contains the program code and any necessary variables and statements.

To create a program that calculates the sum of two numbers and outputs the result, the following code can be used:

public static void main(String[] args) {
   int num1 = 5;
   int num2 = 7;
   int sum = num1 + num2;
   System.out.println("The sum of " + num1 + " and " + num2 + " is " + sum);
}

In this example, two integer variables num1 and num2 are assigned the values 5 and 7, respectively. The sum variable is then assigned the value of the sum of num1 and num2. Finally, the output is displayed using the System.out.println() method.

Use

Java programs can be used to perform a wide variety of tasks, from simple calculations to complex data processing operations. They are widely used in software development, web applications, mobile applications, and many other areas.

Important Points

• Java programs typically begin with the main() method.
• Programs can be used to perform a wide range of tasks.
• The syntax of a Java program includes variables, statements, and methods.
• Proper coding practices such as commenting and code organization are important for creating readable and maintainable programs.

Summary

Java programs are a powerful tool for performing a wide range of tasks. They typically begin with the main() method and include variables, statements, and methods. Proper coding practices are important for creating programs that are readable and maintainable.
