Java Question

java howto ArrayList push, pop, shift, and unshift

I've determined that a Java

ArrayList.add
is similar to a JavaScript
Array.push


I'm stuck on finding
ArrayList
functions similar to the following


  • Array.pop

  • Array.shift

  • Array.unshift
    I'm leaning toward
    ArrayList.remove[At]



The last one is the most important for what I'm working on now (Android). Thanks in advance!

Answer

ArrayList is unique in its naming standards. Here's the equivalencies:

Array.pop     -> ArrayList.remove(int index);
Array.shift   -> ArrayList.remove(0);
Array.unshift -> ArrayList.add(int index, Object o); //Index would be 0
