java howto ArrayList push, pop, shift, and unshift

Question

I\'ve determined that a Java ArrayList.add is similar to a JavaScript Array.push

I\'m stuck on finding ArrayList functions sim

Answer 1

maybe you want to take a look java.util.Stack class. it has push, pop methods. and implemented List interface.

for shift/unshift, you can reference @Jon's answer.

however, something of ArrayList you may want to care about , arrayList is not synchronized. but Stack is. (sub-class of Vector). If you have thread-safe requirement, Stack may be better than ArrayList.
