Scanner Class in Java (Take Input From User in Java)

Scanner Class in Java:

Scanner Class in Java allows us to input or read the primitive data types. It is a class in java.util package used for obtaining the input of primitive types like int, double, and strings. It is one of the easiest ways to receive input in a Java program. The java.util.Scanner is a simple text scanner that can parse primitive types and strings using regular expressions. A scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.

Example 1: Using one String and one Integer in the code as shown below.

package com.main;

import java.util.Scanner;

public class Scanner_class {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		Scanner scanner = new Scanner(System.in);
		
		System.out.println("What is your Website Name? ");
		String web_name = scanner.nextLine();
		
		System.out.println("How old is your Website? ");
		int web_age = scanner.nextInt();
		

		System.out.println("Hi " + web_name);
		System.out.println("You are " + web_age + " years old");
		
		
		
	}

}

Example 2: Using two String and one Integer in the code as shown below.

package com.main;

import java.util.Scanner;

public class Scanner_class {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		Scanner scanner = new Scanner(System.in);
		
		System.out.println("What is your Website Name? ");
		String web_name = scanner.nextLine();
		
		System.out.println("How old is your Website? ");
		int web_age = scanner.nextInt();
		
		scanner.nextLine();
		
		System.out.println("Which subject you teach? ");
		String web_subject = scanner.nextLine();
		
		
		System.out.println("Hi " + web_name);
		System.out.println("You are " + web_age + " years old");
		System.out.println("You teach " + web_subject);
		
		
	}
