In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.Scanner;
public class Javaexcercise
{
    public static void main(String[] args) 
    {
        int num, x, flag = 0, i = 0;
        Scanner s = new Scanner(System.in);
        System.out.print("Enter no. of elements you want in array:");
        num = s.nextInt();
        int a[] = new int[num];
        System.out.println("Enter all the elements:");
        for(i = 0; i < num; i++)
        {
            a[i] = s.nextInt();
        }
        System.out.print("Enter the element you want to find:");
        x = s.nextInt();
        for(i = 0; i < num; i++)
        {
            if(a[i] == x)
            {
                flag = 1;
                break;
            }
            else
            {
                flag = 0;
            }
        }
        if(flag == 1)
        {
            System.out.println("Element found at position:"+(i + 1));
        }
        else
        {
            System.out.println("Element not found");
        }
    }
}

Result:

Enter no. of elements you want in array: 5

Enter all the elements:

10

20

30

40

50

Enter the element you want to find: 20

Element found at position: 2
