java - Method taking in 2 arguments (array of ints, and a single int) -

i've created method, that, given array of numbers , integer n, calculates longest occurrence of integer n. example 1 0 0 0 1 1 1 1, given number 1, longest sequence 4. i'm using 0's , 1's @ moment keep simple, i'm stuck on implementing main method test function - i'm not sure how separate integer "n" , array of ints when reading command line, , i'm hoping given pointers/help. here's code:

public class oneb {  public static int longestseq(int[] nums, int n) {       int max = 0;     int curlength = 0;      (int = 0; < nums.length; i++) {         if (i == n) {             curlength++;             if (curlength > max)                 max = curlength;         } else             curlength = 0;     }     return max; }   public static void main(string[] args) {        int[] nums = new int[args.length-2];     int n = integer.parseint(args[args.length-1]);      (int = 0; args.length-1 > i; i++) {         nums[i] = integer.parseint(args[i]);     }       int result = longestseq(nums, n);     system.out.println(result);         } } 

what i'm aiming last number in command line used integer n, whilst before used array nums.

with input 1 1 0 0 0 1 1 1 1 1 (the last 1 being "n" value - 4 being expected output") error:

exception in thread "main" java.lang.arrayindexoutofboundsexception: 8 @ oneb.main(oneb.java:26) 

check javadoc arrayoutofbounds. put break point in code (you have information needed figure out line) , step through code slowly, watching values of all variables.
