Comment

//Description: A programming tutorial on getting user input for string, int, double and char data types in Java.
//_________________________________________________________________________________________________________________

//Include the necessary module that gets the user input.

import java.util.Scanner;

public class user_input{  // NB: the class name should be the same as ur file name e.g. spaXXE's is user_input.java
	
	public static void main(String[] args){ 
		
			// create a Scanner object.
		
			Scanner scan = new Scanner(System.in); 
			
			 // prompt user for data input; the first one here is a string.
			System.out.println("\t__________________________");
			System.out.println("\n\tYowza,let's get started!!!");
			System.out.println("\t__________________________\n");
			System.out.println("\nEnter your name:");
			// get the user input and store it inside a variable.
			
			String name = scan.next();
	
			/* USER INPUT: AN INTEGER. */
			
			System.out.println("Now, Enter your age: "); // prompt user for data input 
			int age = scan.nextInt();
			
			/* USER INPUT: A SINGLE CHARACTER. */
			
			System.out.println("Mmh, btw...What's the first letter of the alphabet, lowercase?:"); 
			char alphabet = scan.next().charAt(0);
			
			/* USER INPUT: THE DOUBLE DATA TYPE. */
			
			System.out.println("Thank goodness,  you are not a robot. I got a pi, round it to 4 d.p:"); 
			double pi = scan.nextDouble();

			// display the output in a stylistic format. (.-.)
			
			System.out.println("\n\t\t _________________________________");
			System.out.println("\t\t|                                 |");
	        System.out.println("\t\t|Here is a summary of your data...|");
			System.out.println("\t\t|_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _|");
			System.out.println("\t\t|_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _|");
			// display the user input.
		    System.out.println("\t\t|Name: " + name + "                     |");
			System.out.println("\t\t|Age: " + age + "                          |");
		    System.out.println("\t\t|Alphabet: " + alphabet + "                      |");
			System.out.println("\t\t|Pi: " + pi + "                        |");
			System.out.println("\t\t|_________________________________|\n\n");

	}
}

/*                  RUNNING INSTRUCTIONS.

i.   Open cmd and navigate to the folder containing the java file using the cd <path-to-file> command.
ii.  Compile the java file using javac <filename.java>; a <filename.class> will be generated when the code is error-free.
iii. Run the file using java <filename>.
iv.  Have fun interacting with the program.
