Hello and Name Printer

Write a Java program to print 'Hello' on screen and your name on a separate line.

Pictorial Presentation:

Java: Print hello and your name on a separate lines

Sample Solution:

Java Code:

public class Exercise1 { 
    public static void main(String[] args) {
        // Print a greeting message to the console
        System.out.println("Hello\nAlexandra Abramov!");
    } 
}

Explanation:

In the exercise above

The "main()" method is the program entry point.
It uses System.out.println to print the message.
The message consists of two lines: "Hello" and "Alexandra Abramov!" separated by a newline character (\n).

When we run this Java program, we'll see this message displayed in the console or terminal.

Sample Output:

Hello                                                                                                      
Alexandra Abramov!

Sample solution using input from the user:

Java Code:

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        // Create a Scanner object to read input from the console
        Scanner input = new Scanner(System.in);
        // Prompt the user to input their first name
        System.out.print("Input your first name: ");
        String fname = input.next();
        // Prompt the user to input their last name
        System.out.print("Input your last name: ");
        String lname = input.next();
        // Output a greeting message with the user's full name
        System.out.println();
        System.out.println("Hello \n" + fname + " " + lname);
    }
}

Explanation:

In the exercise above -

import java.util.Scanner;: This code imports the "Scanner" class, which allows the program to read input from the user.
public class Main {: This code declares a class named "Main," and it contains the main method, which is the entry point of the program.
public static void main(String[] args) {: This line defines the main method. Here's what each part means:

public: This keyword indicates that the method can be accessed from outside the class.
static: This keyword means that the method belongs to the class itself, not to a specific instance of the class.
void: This specifies that the main method doesn't return any value.
main: This is the name of the method.
(String[] args): This is the method's parameter list, which accepts an array of strings. In this case, it's not used.

Scanner input = new Scanner(System.in);: This code creates a Scanner object named input to read input from the console (user's keyboard).
System.out.print("Input your first name: ");: This code prints a message to the console, asking the user to input their first name.
String fname = input.next();: This code reads the user's input for their first name and stores it in the variable fname.
System.out.print("Input your last name: ");: This code prints a message to the console, asking the user to input their last name.
String lname = input.next();: This code reads the user's input for their last name and stores it in the variable lname.
System.out.println();: This code prints a blank line to separate the output.
System.out.println("Hello \n" + fname + " " + lname);: This code prints a greeting message to the console. It combines the user's full name with the text "Hello" and a newline character (\n) to create a formatted greeting message.

Sample Output:

Input your first name:  James 
Input your last name:  Smith

Hello 
James Smith

For more Practice: Solve these Related Problems:

Modify the program to ask for user input and print "Hello, [Name]" dynamically.
Print "Hello" in uppercase and your name in lowercase using string manipulation.
Print "Hello" and your name, but each letter should be on a new line.
Print "Hello" and your name, but reverse the order of characters.
