Question

java Elements in a range Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain fewer than 20 integers. That list is followed by two more integers representing lower and upper bounds of a range. Your program should output all integers from the list that are within that range (inclusive of the bounds). For coding simplicity, follow each output integer by a comma, even the last one. The output ends with a newline. Ex: If the input is: 5 25 51 0 200 33 0 50 then the output is: 25,0,33, (the bounds are 0-50, so 51 and 200 are out of range and thus not output). To achieve the above, first read the list of integers into an array.

Answer 1

Answer:

The program in Java is:

import java.util.Scanner;

public class MyClass {

   public static void main(String args[]) {

     Scanner input = new Scanner(System.in);

     int n;

     n = input.nextInt();

     int [] mylist = new int[n+1];

     mylist[0] = n;

     System.out.print("List elements: ");

     for(int i = 1;i<n+1;i++){

         mylist[i] = input.nextInt();

     }

     int min,max;

     System.out.print("Min & Max: ");

     min = input.nextInt();

     max = input.nextInt();

     

     for(int i=1; i < mylist.length; i++){

         if(mylist[i]>=min && mylist[i]<=max){

             System.out.print(mylist[i]+" ");

 }

}

   }

}

Explanation:

This line declares length of list

     int n;

This line gets length of list

     n = input.nextInt();

This line declares the list/array

     int [] mylist = new int[n+1];

This line initializes the element at index 0 to the length of the list

     mylist[0] = n;

This prompts user for elements of the list/array

     System.out.print("List elements: ");

The following iteration gets list elements

     for(int i = 1;i<n+1;i++){

         mylist[i] = input.nextInt();

     }

This declares the lower and upper bound (min, max)

     int min,max;

This line prompts user for elements of the list/array

     System.out.print("Min & Max: ");

This next two lines get the bound of the list/array

     min = input.nextInt();

     max = input.nextInt();

The following iteration prints the elements in the range

     for(int i=1; i < mylist.length; i++){

         if(mylist[i]>=min && mylist[i]<=max){

             System.out.print(mylist[i]+" ");

 }
