Print the count of the longest sequence in an array.

Question :  Write a program to print the count of the longest sequence in the input array

Lets take an example of

input: 1,2,14,3,4,5,10,7,8,9,10,11,12,13,14,15
output: 9

Here we have sequence 1,2              count=2
                                     3,4,5           count=3
                                     7,8,..15       count=9

So the output should be 9.

public class LongSequence {

public static int printCounter(int[] arg) {

int counter = 1;
int resultCounter = 0;
for (int i = 0; i < arg.length - 1; i++) {
if (arg[i] + 1 == arg[i + 1]) {
++counter;
} else {
if (counter >= resultCounter) {
      resultCounter = counter;
}
counter=0;
}
}
System.out.println(resultCounter);
                return resultCounter;
}

}
