Chapter 1- Getting User Input in Java

• Reading data from the Keyboard

In order to read data from the keyboard, Java has a scanner class.

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

Scanner S = new Scanner(System.in);  //(Read from the keyboard)
int a = S.nextInt();  //(Method to read from the keyboard)

Code As Described in the Video

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

public class CWH_05_TakingInpu {
    public static void main(String[] args) {
        System.out.println("Taking Input From the User");
        Scanner sc = new Scanner(System.in);
//        System.out.println("Enter number 1");
//        int a = sc.nextInt();
//        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 numbers is");
//        System.out.println(sum);
//        boolean b1 = sc.hasNextInt();
//        System.out.println(b1);
//        String str = sc.next();
        String str = sc.nextLine();
        System.out.println(str);

    }
