2021-4-13 · Writing a Java program to remove element from an array may look like a simple task but it comes with its own set of problems. Those problems stem from the fact that array in Java is fixed in length. Which means you can't just remove an element from the given index in an array, you will need to shift all the elements that are after the element that has to be removed, to the left to fill the gap

// it looks like right now objects want to be powers of 2 minus 8 // and the array size eats another 4 bytes /** * ArrayUtils contains some methods that you can call to find out * the most efficient increments by which to grow arrays.
