Java Program for Linear search in an array

This Program will takes three input 

1. for the size of array
2. for array 
3. Number to search in array

Explanation 

In this program loop will go upto the value of n-1 or i<n then m is compared to value of arr[i] if the value is in array then it return the value of i else -1;

import java.util.*;
public class Main {
    public static void main(String args[]) {
        Scanner sc=new Scanner(System.in);
        int n=sc.nextInt();
        int[] arr=new int[n];
        for(int i=0;i<n;i++)
        {
            arr[i]=sc.nextInt();
        }
        int m=sc.nextInt();
        System.out.println(linearsearch(arr, m));
    }
    public static int linearsearch(int []arr,int m) 
    {
        for(int i=0;i<arr.length;i++)
        {
            if(arr[i]==m)
            {
                return i;
            }
        }
        return -1;
    }
