Input FormatThere are three lines of input:The first line contains an integer.The second line contains a double.The third line contains a String.Output FormatThere are three lines of output:On the first line, print String: followed by the unaltered String read from stdin.On the second line, print Double: followed by the unaltered double read from stdin.On the third line, print Int: followed by the unaltered integer read from stdin.To make the problem easier, a portion of the code is already provided in the editor.Note: If you use the nextLine() method immediately following the nextInt() method, recall that nextInt() reads integer tokens; because of this, the last newline character for that line of integer input is still queued in the input buffer and the next nextLine() will be reading the remainder of the integer line (which is empty).Sample Input423.1415Welcome to HackerRank's Java tutorials!Sample OutputString: Welcome to HackerRank's Java tutorials!Double: 3.1415Int: 42

Solution

This problem is about reading and printing different types of inputs in Java. Here is a step-by-step solution:

  1. First, you need to import the Scanner class from the java.util package. This class provides methods to read inputs of different types.
import java.util.Scanner;
  1. Create an instance of the Scanner class. This will be used to read the inputs.
Scanner scan = new Scanner(System.in);
  1. Read the integer input. The nextInt() method of the Scanner class can be used for this.
int i = scan.nextInt();
  1. Read the double input. The nextDouble() method of the Scanner class can be used for this.
double d = scan.nextDouble();
  1. Read the String input. Here, you need to use the nextLine() method twice. The first call is to consume the newline character left in the buffer after reading the double. The second call is to actually read the String.
scan.nextLine();
String s = scan.nextLine();
  1. Print the inputs in the required format.
System.out.println("String: " + s);
System.out.println("Double: " + d);
System.out.println("Int: " + i);
  1. Finally, don't forget to close the Scanner object after you're done using it.
scan.close();

So, the complete code would look like this:

import java.util.Scanner;

public class Solution {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        double d = scan.nextDouble();
        scan.nextLine();
        String s = scan.nextLine();

        System.out.println("String: " + s);
        System.out.println("Double: " + d);
        System.out.println("Int: " + i);

        scan.close();
    }
}

in java Arun needs to create a program that handles user input by converting a float value to both double and integer formats. Write a program for him that reads a float value entered by the user, converts it to double with one decimal place and integer type, and displays the results. Input format : The input consists of a float value f. Output format : The output prints the converted double value, rounded off to one decimal place, followed by the converted integer. Separate the values using (;).

Complete the code in the editor below. The variables , , and are already declared and initialized for you. You must:Declare variables: one of type int, one of type double, and one of type String.Read lines of input from stdin (according to the sequence given in the Input Format section below) and initialize your variables.Use the operator to perform the following operations:Print the sum of plus your int variable on a new line.Print the sum of plus your double variable to a scale of one decimal place on a new line.Concatenate with the string you read as input and print the result on a new line.Note: If you are using a language that doesn't support using for string concatenation (e.g.: C), you can just print one variable immediately following the other on the same line. The string provided in your editor must be printed first, immediately followed by the string you read as input.Input FormatThe first line contains an integer that you must sum with .The second line contains a double that you must sum with .The third line contains a string that you must concatenate with .Output FormatPrint the sum of both integers on the first line, the sum of both doubles (scaled to decimal place) on the second line, and then the two concatenated strings on the third line.
