User Input in JAVA

Reading data from keyboard:

In order to read data from keyboard, JAVA has a Scanner class.

Scanner class has a lot of to read the data from the keyboard.

    Scanner s = new Scanner (System.in) [Read from the keyboard]

    int a = s.nextInt(); [Method to read data from the keyboard (Integer in this case)]

Code:

package com.company;
import java.util.Scanner;

public class Tut4 {
    public static void main(String[] args) {
        System.out.println("Taking Input from User");
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter Number 1");
//        int a = sc.nextInt();
//        we can use float to calculate between decimal numbers
        float a = sc.nextFloat();
        System.out.println("Enter Number 2");
//        int b = sc.nextInt();
        float b = sc.nextFloat();
//        int sum = a+b;
        float sum = a+b;
        System.out.println("The Sum of these number is \n");
        System.out.println(sum);
//        boolean b1 = sc.hasNextInt();
//        System.out.println(b1);
//        String str = sc.next(); //do not read after space.
        String str2 = sc.nextLine(); // whole line reading.
        System.out.println(str);
    }
