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

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 method. If value is found ,
  display message “Found” with its position where it is present in the array. Otherwise
  display message “not found”.

Solution:

 
import java.util.*; 
  class LinearSearch 
  { 
      public static void main(String args[]) 
      {
          double a[] = new double[20]; 
          Scanner sc = new Scanner(System.in); 
          System.out.println("Enter 20 values in Array"); 
          for(int i=0; i< 20; i++) 
          { 
              a[i] = sc.nextDouble(); 
          } 
          System.out.println("Enter the value to be searched?"); 
          double x = sc.nextDouble(); 
          int pos = -1; 
          for(int i=0; i< a.length; i++) 
          { 
              if(a[i] == x) 
              { pos = i; break; 
              } 
          } 
          if(pos != -1) 
              System.out.println("Element is found at "+(pos+1)); 
          else 
              System.out.println("Element is not found.");   
      }
  }
