Inputs in Java

Explore the different cores of java programming below

Inputs in Java: Overview

In Java, obtaining user input is an essential part of creating interactive applications.

Getting Input from a User

To get input from the user, you first need to create an instance of the Scanner class.

Performing Actions with Inputs

Once input is obtained, it can be processed to perform various actions.

Example 1: Getting a User's Name and Greeting Them







import java.util.Scanner;

public class UserInputExample {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
              
// Prompting the user
System.out.print("Enter your name: ");
String name = scanner.nextLine();
              
// Greeting the user
System.out.println("Hello, " + name + "! Welcome to Java programming.");
                      
scanner.close();
}
}
Output:

input: Enter your name: fortune


output: Hello, fortune Welcome to Java programming.





Example 2: Performing Arithmetic Operations java Copy code 




import java.util.Scanner;

public class ArithmeticOperations {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
                  
// Getting two numbers from the user
System.out.print("Enter the first number: ");
int num1 = scanner.nextInt();
                  
System.out.print("Enter the second number: ");
int num2 = scanner.nextInt();
                  
// Performing and displaying operations
int sum = num1 + num2;
int product = num1 * num2;
                  
System.out.println("The sum of the numbers is: " + sum);
System.out.println("The product of the numbers is: " + product);
                  
scanner.close();
}
}
Output:

Enter the second number: 2

Enter the second number: 3

The sum of the numbers is: 5

The product of the numbers is: 6

Example 3: String Manipulation




import java.util.Scanner;

public class StringManipulation {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
                  
// Getting a string from the user
System.out.print("Enter a phrase: ");
String phrase = scanner.nextLine();
                  
// String manipulations
System.out.println("Uppercase: " + phrase.toUpperCase());
System.out.println("Lowercase: " + phrase.toLowerCase());
System.out.println("Length: " + phrase.length());
                  
scanner.close();
}
}
Output:

Enter a phrase: i love programing

Uppercase: i love programing

Lowercase: i love programing

Length: 16
