Java : Getting User Input

 


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

public class Taking_Input{
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Taking Input from User");
        System.out.println("Enter First Number");
        int a = sc.nextInt();
        System.out.println("Enter second number");
        int b = sc.nextInt();
        int sum = a+b;
        System.out.println(sum);

        System.out.println("Taking user name");
        String str = sc.next();
        System.out.println(str);

        boolean bool = sc.hasNextInt();
        System.out.println(bool);

    }
}

Exercise :- 

1. Write a program to calculate the percentage of a given students in CBSC board exam . His
   Marks from 5 subjects must be taken as input from the keyboard (Marks are out of 100)
import java.util.Scanner;

public class Excercise{
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter The Marks which u get in your CBSE Board");
        System.out.println("Enter The Marks of Hindi");
        int a = sc.nextInt();
        System.out.println("Enter The Marks of English");
        int b = sc.nextInt();
        System.out.println("Enter The Marks of Maths");
        int c = sc.nextInt();
        System.out.println("Enter The Marks of Science");
        int d = sc.nextInt();
        System.out.println("Enter The Marks of Computer");
        int e = sc.nextInt();
        System.out.println("The Total numbers of subjects are :");
        int sum = a+b+c+d+e;
        System.out.println(sum);
        System.out.print("Percentage = ");
        float f = sc.nextFloat();
        float per = sum/f;
        System.out.print(per);
        System.out.print("%");
    }
}
