Solution
The challenge is to read an integer, a double, and a string from the standard input (stdin), then print the values in a specific format. Here's how you can do it:
- Import the necessary classes:
import java.io.*;
import java.util.*;
- Define the main class and the main method:
public class Solution {
public static void main(String[] args) {
- Create a Scanner object to read input:
Scanner scanner = new Scanner(System.in);
- Read the integer, double, and string values:
int Myint = scanner.nextInt();
double d = scanner.nextDouble();
scanner.nextLine(); // This line is important to move the scanner to the next line
String mystring = scanner.nextLine();
- Print the values in the required format:
System.out.println("String: " + mystring);
System.out.println("Double: " + d);
System.out.println("Int: " + Myint);
- Close the main method and the main class:
}
}
The complete code would look like this:
import java.io.*;
import java.util.*;
public class Solution {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int Myint = scanner.nextInt();
double d = scanner.nextDouble();
scanner.nextLine(); // This line is important to move the scanner to the next line
String mystring = scanner.nextLine();
System.out.println("String: " + mystring);
System.out.println("Double: " + d);
System.out.println("Int: " + Myint);
}
}
This code will read an integer, a double, and a string from the standard input, and then print them in the required format.

In this challenge, you must read integers from stdin and then print them to stdout. Each integer must be printed on a new line. To make the problem a little easier, a portion of the code is provided for you in the editor below.
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 (;).
