Java ArrayList.remove() is a method in the Java ArrayList class that removes the element at a specified index or removes the first occurrence of a given element. It shifts subsequent elements to the left and adjusts the size of the list. Introduced in Java 1995 with Java 1.2, remove() is commonly used for modifying lists by removing items based on their index or value, and is a fundamental method for dynamic list manipulation.
