This is a simple Java program that reads input from the user and echoes it back.

• The program uses a Scanner to read user input.
• It then prints that input back with the prefix "Echo:".

You can run this code using any Java compiler. Here's a quick way using an online compiler:

• Visit: [https://www.programiz.com/java-programming/online-compiler/]
• Paste the code from src/Main.java
• (Optional) Click the stdin tab and enter some input like: Hello world
• Click Run

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
      Scanner scanner = new Scanner(System.in);
      System.out.print("Enter text: ");
      String input = scanner.nextLine();
      System.out.println("Echo: " + input);
  }
}
