Question

5.16 *zyLab: Hello IDE The goal of this problem is learn how to use Eclipse or IntelliJ. Submit the source code files (.java) below. Make sure your source files are encoded in UTF-8. Some strange compiler errors are due to the text encoding not being correct. Complete the following: In your chosen IDE, create a new project. You can name the project anything you like, we recommend "M5". Create a new class file, titled HelloIDE (which will create the file HelloIDE.java). Write a main method in this class that prompts a user for their name, and then replies with "Hello, ___!" filling in the blank with the typed in name, trimmed. Otherwise, if the string is empty, or just contains only whitespace, or if no input is given, output "Hello, stranger!". Example input/output for input "Mark":

Answer 1

To complete the assignment, create a new project and class file in Eclipse or IntelliJ. Write a main method for user input where you print out a personal greeting or "Hello, stranger!" if no name is provided. Ensure the encoding is set to UTF-8.

Step-by-step explanation:

To create a simple program in your chosen IDE that greets a user by their name, follow these steps:

1. Open Eclipse or IntelliJ and create a new project. You may name it M5 or any other name you prefer.
2. In the project, create a new class file named HelloIDE. This will automatically create a file called HelloIDE.java.
3. Inside the HelloIDE.java file, write a main method that includes functionality for user input. If the user provides a name, the program will greet them by that name, after trimming any whitespace. If the input is empty or contains only whitespace, the program will respond with "Hello, stranger!".

Here is an example snippet of Java code that accomplishes this:

import java.util.Scanner;

public class HelloIDE {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Please enter your name: ");
String name = scanner.nextLine().trim();
if(name.isEmpty()) {
System.out.println("Hello, stranger!");
} else {
System.out.println("Hello, " + name + "!");
}
scanner.close();
}
}

Remember to save your files and ensure they are encoded in UTF-8 to avoid compiler errors related to text encoding.
