Java ArrayList.contains() is a method in the Java ArrayList class that checks if the list contains the specified element. It uses the Java equals() method to compare elements. If the element is found, it returns true; otherwise, it returns false. Introduced in Java 1995 with Java 1.2, contains() is commonly used in Java applications to check for membership or presence of an element in dynamic lists.
