Define a class to accept values into an array of double data type of size 20. Accept a double value from user and search in the array using linear search…

import java.util.Scanner;

public class KboatLinearSearch

    public static void main(String args[]) 
    {
        Scanner in = new Scanner(System.in);
        
        double arr[] = new double[20];
        int l = arr.length;
        int i = 0;
        
        System.out.println("Enter array elements: ");
        for (i = 0; i < l; i++) 
        {
            arr[i] = in.nextDouble();    
        }
        
        System.out.print("Enter the number to search: ");
        double n = in.nextDouble();
        
        for (i = 0; i < l; i++)
