* Asks user for a number between low and high (inclusive), reads it and returns

Question

* Asks user for a number between low and high (inclusive), reads it and returns it.
   * Read from the provided Scanner and write too the PrintStream
   * Keeps reading until user enters a number within range (inclusive). USE a while (or do-while) loop
   * @param in - The Scanner to read from
   * @param low - the lowest acceptable number
   * @param high - the highest acceptable number
   * @return the number read
   * Your implementation needs to use a while or do-while loop
   */
   public static int readWithinRange(Scanner in, PrintStream out, int low, int high)
   {
       return 0;

Explanation / Answer

ReadNumInrange.java

package org.students;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintStream;
import java.util.Scanner;

public class ReadNumInrange {
  

   public static void main(String[] args) throws Exception {
       //Declaring variables
   int low,high;
   int number=0;
  
   //Scanner object is used to get the inputs entered by the user
   Scanner in=new Scanner(System.in);
  
//Getting the minimum number
   System.out.println("Enter the minimum value :");
   low=in.nextInt();
  
   //Getting the maximum number
   System.out.println("Enter the maximum value :");
   high=in.nextInt();
  
   FileOutputStream fout=new FileOutputStream("D: umbs.txt");
   PrintStream out=new PrintStream(fout);

   //calling the method to read the number
number=readWithinRange(in,out,low,high);
  
   //This loop continues to execute until the user enters a number within the range
   while(number>=low && number<=high)
   {
   //Printing the data to the output stream file
   out.println(number);
       //calling the method to read the number
   number=readWithinRange(in,out,low,high);
  
   }
   out.close();
   fout.close();
     
     

   }

   //reading the number from the user within the range
   private static int readWithinRange(Scanner in, PrintStream out, int low,
           int high) {
      
       System.out.print("Enter a number between "+low+"-"+high+":");
      
       return in.nextInt();
   }

}

______________

output:

Enter the minimum value :
5
Enter the maximum value :
50
Enter a number between 5-50:25
Enter a number between 5-50:35
Enter a number between 5-50:45
Enter a number between 5-50:15
Enter a number between 5-50:33
Enter a number between 5-50:44
Enter a number between 5-50:55

______________
