Question

Prompt the user to input an integer, a double, a character, and a string, storing each into separate variables. Then, output those four values on a single line separated by a space.

Answer 1

Following are the program in java language:

import java.util.*; // import package

public class Main

{

public static void main(String[] args) // main method

{

int num; // integer variable declaration

double r; //double varaible declaration

char ch; // char variable declaration

Scanner scnr=new Scanner(System.in); // creating the instance of scanner

System.out.println("Enter the string:");

String str=scnr.nextLine(); // reda string by user

System.out.println("Enter the integer value:");

num=scnr.nextInt(); // Read integer value by the user

System.out.println("Enter the Double value:");

r=scnr.nextDouble(); // read double value by user

System.out.println("Enter the character value:");

ch= scnr.next().charAt(0); // read character by user

System.out.print(num + " ,"); // display them in a single line

System.out.print( " " +r +" ,");//dislpay in a single line

System.out.print( " " +ch +",");//dislpay in a single line

System.out.print(" " +str);//dislpay in a single line

}

}

Output:

Enter the string:

ram

Enter the integer value:

34

Enter the Double value:

45.789

Enter the character value:

r

34 , 45.789 , r, ram

Step-by-step explanation:

Following are the description of program

• Read the integer ,string,char,double value by the user by using scanner class in "num","str","ch" and "r" variable respectively

• Print that value in a single line separated by comma by System.out.println statement.
