Question

trying to write code underneath the appropriate comment. Needs to ask user to enter in a positive integer 5 times. Need to print out each integer after its entered. Using a call to method inputInteger. Here is the code so far

package lab2Package;

import java.util.Scanner;

public class Lab2Class

{

public static void main(String[] args)

{

//declare variables

String name;

int userNum;

//initialize variables

name = inputString("Enter your name ");

//enter your name at the keyboard

System.out.println("My name is "+ name);

//enter 5 integers at the keyboard and print it out

System.out.println("Integers from Keyboard");

//enter 5 decimal numbers at the keyboard and print each one out

System.out.println("Decimal values from keyboard");

//generate 20 random numbers and print each one out

System.out.println("Random numbers between one and two inclusively");

}//end main

//

// inputString

//

// the purpose of this method is to input a string from the keyboard

//

// Input: prompt the prompt message for the dialog box

//

// Return: inputStr the string that was entered at the keyboard

//

public static String inputString(String prompt)

{

Scanner input = new Scanner(System.in);

String inputStr;

//prompt user to enter in string

System.out.print(prompt);

//read in value as string from keyboard

inputStr = input.nextLine();

//return input string

return(inputStr);

}//end input string

//

// inputInteger

//

// the purpose of this method is to input an integer value form the keyboard

//

// Input: prompt the prompt message for the user

//

// Return: num the integer entered at the keyboard

//

public static int inputInteger(String prompt)

{

Scanner input = new Scanner(System.in);

String cleanUpStr;

int num;

num = 0;

cleanUpStr = "no string yet";

System.out.println(prompt);

num = input.nextInt();

cleanUpStr = input.nextLine();

return(num);

}//end inputInteger

}//end lab2

Explanation / Answer

package lab2Package; import java.util.Random; import java.util.Scanner; public class Lab2Class { public static void main(String[] args) { //declare variables String name; int userNum; double decimalValue; //initialize variables //enter your name at the keyboard name = inputString("Enter your name "); //enter 5 integers at the keyboard and print it out for(int i = 0; i < 5; ++i) { userNum = inputInteger("Enter an integer: "); System.out.println("You entered " + userNum); } //enter 5 decimal numbers at the keyboard and print each one out System.out.println("Decimal values from keyboard"); Scanner input = new Scanner(System.in); for(int i = 0; i < 5; ++i) { System.out.print("Enter a decimal value: "); decimalValue = input.nextDouble(); System.out.println("You entered " + decimalValue); } //generate 20 random numbers and print each one out System.out.println("Random numbers between one and two inclusively"); Random random = new Random(); for(int i = 0; i < 20; ++i) { System.out.println(random.nextDouble() + 1); } }//end main // // inputString // // the purpose of this method is to input a string from the keyboard // // Input: prompt the prompt message for the dialog box // // Return: inputStr the string that was entered at the keyboard // public static String inputString(String prompt) { Scanner input = new Scanner(System.in); String inputStr; //prompt user to enter in string System.out.print(prompt); //read in value as string from keyboard inputStr = input.nextLine(); //return input string return(inputStr); }//end input string // // inputInteger // // the purpose of this method is to input an integer value form the keyboard // // Input: prompt the prompt message for the user // // Return: num the integer entered at the keyboard // public static int inputInteger(String prompt) { Scanner input = new Scanner(System.in); String cleanUpStr; int num; num = 0; cleanUpStr = "no string yet"; System.out.println(prompt); num = input.nextInt(); cleanUpStr = input.nextLine(); return(num); }//end inputInteger }//end lab2
