Solution
Sure, I can help with that. This is a simple Java program that takes an integer input from the user and prints it on the screen. Here's a step-by-step explanation:
-
import java.io.*; import java.util.Scanner;- These are import statements. They are used to include built-in Java packages into the program. Thejava.iopackage contains classes for system input and output through data streams, serialization and the file system. Thejava.util.Scannerclass is used to get input from the user. -
class GFG { ... }- This is the declaration of the class. In Java, every application must contain a main class that wraps up all the code. Here, the class is namedGFG. -
public static void main(String[] args) { ... }- This is the main method. It's the entry point for any Java application. The Java Virtual Machine (JVM) calls the main method when the program starts. -
int num;- This is a declaration of an integer variablenum. This variable will be used to store the integer input from the user.
