Question

Java write code that inserts useritems into the output string stream itemsoss until the user enters "exit". each item should be followed by a space. sample output if user input is "red purple yellow exit": red purple yellow

Answer 1

If you're a zybooks user.

itemsOSS.print(userItem + " "); 
      userItem = itemCharStream.toString();

Answer 2

For the given problem, first read the input from console using scanner class. Then print the input into the print writer and scan the next word using the scanner. This will continues until we did not get ‘Exit’ word. The loop will terminate when user enter exit. Now, append the text and print the string.  

Further Explanation:  

Code: The below Java code that inserts the user items into output stream items until the user enters “exit”.  

// Scanner class to take input from the keyboards

import java.util.Scanner;  

//Enables to find the characters written to a writer as a string

import java.io.StringWriter;  

// Used to print the objects in text-output stream

import java.io.PrintWriter;  

//class definition

public class UserInputsOutputs

{  

   public static void main (String [] args)  

   {  

//Scanner class to read the input  

        Scanner scan = new Scanner(System.in);  

        String userItem = "";  

// printwriter to print items on the console.  

        StringWriter itemCharStream = new StringWriter();  

        PrintWriter stringItems = new PrintWriter(itemCharStream);  

        System.out.println("Enter items (type Exit to quit):");  

        userItem = scan.next();  

// Loop terminates when user enter Exit  

        while (!userItem.equals("Exit"))  

        {  

            stringItems.append(userItem+" ");  

            userItem = scan.next();  

        }  

        userItem = itemCharStream.toString();  

// Display the string  

        System.out.println(userItem);  

        return;  

   }  

}
