Here's a simple example of Python code:
# This is a simple Python program to greet someone
name = input("What's your name? ")
print(f"Namaste, {name}! Welcome to the world of Python!")
Java: The Reliable Workhorse
Now, let's talk about Java. If Python is your cool, easygoing friend, Java is like that disciplined dai or didi who always gets the job done. Here's what makes Java special:
- Platform Independence: Java follows the "Write Once, Run Anywhere" principle. This means you can write Java code on your computer in Kathmandu and it will run on any device around the world without changes.
- Object-Oriented: Java is built around the concept of "objects," which makes it great for large, complex applications. Many big companies in Nepal, like F1Soft (the creators of eSewa), use Java for their core systems.
- Strong Typing: Java is very strict about how you declare and use variables. This can be a bit challenging at first, but it helps catch errors early and makes your code more reliable.
- Enterprise-Level Applications: Java is widely used in big business applications, Android app development, and server-side programming. If you dream of working for a multinational company or creating the next big Android app for Nepal, Java is a solid choice.
Here's a simple Java example:
// This is a simple Java program to greet someone
import java.util.Scanner;
public class Namaste {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("What's your name? ");
String name = scanner.nextLine();
System.out.println("Namaste, " + name + "! Welcome to the world of Java!");
}
}
