01 Day : Data Types

Today’s objective to learn Data Types …Primitive & Reference.

> Read 3 variables via Std In;

> Conduct a simple operation on them;

> Print the results via Std Out;

Code :

import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;
public class Solution {
   public static void main(String[] args) {
      int i = 4;
      double d = 4.0;
      String s = “HackerRank “;
      Scanner scan = new Scanner(System.in);
      /* Declare second integer, double, and String variables. */
      int myInt = 0;
      double myDouble = 0.0;
      String myString = “”;
      /* Read and save an integer, double, and String to your variables.*/
      myInt = scan.nextInt();
      myDouble = scan.nextDouble();
      scan.nextLine();
      myString = scan.nextLine();
 
      /* Print the sum of both integer variables on a new line. */
      System.out.println(i + myInt);
      /* Print the sum of the double variables on a new line. */
      System.out.println(d + myDouble);
      /* Concatenate and print the String variables on a new line; 
 the ‘s’ variable above should be printed first. */
      System.out.print(s + myString);
      scan.close();
   }
}
