Hi folks! What is more personal in today's age and times than the 5' inch wonder in your hands or pockets! Well, we just can't get enough of our mobile phones today, whether to checkout a new Youtube video, catch up with friends, book a cab, or cross that nagging next level of clash of clans, we are totally hooked on to our phones. But, it just drives me nuts when I see my app crashing, or just being a tad too slow, when I need its service quick. We can all agree, we don't like that and yet, it happens a lot too often. Here, we are going to list some of the simple reasons why a certain app on your mobile might not be responding well to you.

Why this helps? Well without getting too technical, i would just say that doing so, flushes out the layer that is d...

I am going to give a solution to a rather simple question which is sometimes asked in software programming interviews. " There is one class which has private array list and this array list is initialized in constructor of this class. We have one public method getItem(int i) { ” return ith item of array list” }, We need to know the size of array list. We can only call getItem method.

An arraylist is better for situations where a programmer doesn't know in advance, the number of items he will need to store in an array. For eg. let's say Adam declared an arraylist of size 5. Now, if he needs to add 4 more elements, rather than having to declare a new array each ti...
