![]() ![]() ![]() To remove the element, we only need to write this one line of code: System.arraycopy(array, index + 1, array, index, array.length - index - 1) The simplest pure Java way to do this is to make a new array, one element shorter than the original one and copy all element, except the one we'd like to remove, into it: int copy = new int įor ( int i = 0, j = 0 i < array.length i++) This will create an illusion that a specific element was removed. Instead, to "remove" any element, all subsequent elements need to be shifted backward by one place. Due to the nature of array's memory placement, it is simply impossible to remove the element directly. What makes removing an array element difficult is the fact that all elements are stored sequentially in a single memory block. Furthermore, this happens in O(1) complexity which means it's as fast as it can be. Since all array elements have the same size, this kind of computation leads directly to the element with index 3. If the index of a requested element is 3, the underlying mechanism simply needs to take the memory address of the zero-th element and add three times the size of each element. ![]() When someone wants to access an element at a certain index, pointer arithmetic (which is the mechanism under the hood) allows to quickly and efficiently obtain any particular element. Saturating their air with a non-breathable gas should speed up the process sufficiently.Elements are sequentially stored one after another. Simply vacuuming air out may not be effective because the ants are pretty small and who knows how long it would take for them to breathe through all the oxygen between the keys and the keyboard base. The ants inside are probably not holding onto anything, so you can shake them out of the keyboard and plug it back in. After you're sure the ants are dead, let out the gas inside the bag in conditions that would not result in gas explosion.Better put the plastic bag inside a more protective container, like a jar, in case ants decide to run for their lives and eat through the plastic bag, resulting in a leak. Or it could result in a noticeable explosion. Leave for a day to be sure, but in a place where kids, fire and direct sunlight can't reach it.Let out enough gas so that the plastic bag inflates visibly, and the proportion of the air to gas is small enough to seem deadly for the ants. Press the lighter button, but don't light it, obviously.Suck the air out with your mouth, it should not be dangerous unless your keyboard already contains deadly gases or you tried bug poison earlier.Put the keyboard inside a plastic bag where you can see what's going on inside and have good control of the lighter.Don't attach the keyboard back too soon after taking it out of the freezer though to avoid short circuiting due to possible condensation due to temperature difference.Įxtreme solution: put your notebook in a sealed container, vacuum air out and insert a deadly gas >:) One easy gas is butane from a regular lighter. Don't forget to take out your keyboard from the notebook to avoid blowing something unwanted inside.Īlso you might want to try freezing them. One way is to lure them out with something sweet and then not let them go back inside the keyboard.Īnother is to suck them out with a vacuum cleaner or blow them away with a vacuum cleaner on reverse. ![]()
