Java Inputs

You can already show the data to the users.

Now let's receive it from user.

In java reading the input is a bit complicated

We have a Scanner class in java

the Scanner class have methods to read different type of input.

There are some of it that we use frequently

1. nextLine read the whole input line until found a line separator delimiter.
2. next read the input until found a blank space (Space bar key)
3. nextInt read the input as an Integer
4. nextDouble read the input as a floating point number

You have to use the Scanner class as show here

import java.util.Scanner;

public class LearnInput {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter your name: ");
        String name = sc.nextLine();
        System.out.println("Enter your age: ");
        int age = sc.nextInt();
        System.out.println("Enter your salary: ");
        double salary = sc.nextDouble();
        System.out.println("Your name is " + name);
        System.out.println("Your age is " + age);
        System.out.println("Your salary is " + salary);
        sc.close();
    }
}

first import Scanner class

//Then Codedeclare Explanationa new Scanner object (Here is named sc)

FirstMake we import the java.util.Scannersure to use it.the right data type to the right scanner method

Line 5 : We create a Scanner variable
