count variable is not being incremented Java

I am trying to follow the book which we are given at the University but count variable is not being incremented despite condition is true ... What am I missing here would like to mention I am new to Java 

    public static void main(String[] args) {

    int[] list = new int [] {1, 3, 4, 5, 7, 8, 9, 11, 14};

    int count = 0;  
    for(int i = 0; i < list.length -1; i ++){
            if(list[i] == list[i+1])
                count ++; 

    }
}

if(list[i] == list[i+1]) will always be false. Look at the list; there are no two adjacent values that are equal to each other, which is what your if is testing. So count will always stay 0.

count++; is part of the if wich is always false

your code is equal to :

        if(list[i] == list[i+1]){

            count ++; 
        }

list[i] is always different to list[i+1] 1!=3 3!=4 4!=5 .....

if you want to count you have to put count++ outside the is. And i recommend to always put bracket to if and while to avoid this type of mistake
