How to append elements at the end of ArrayList in Java? -

i wondering, how append element end of arraylist in java? here code have far:

public class stack {      private arraylist<string> stringlist = new arraylist<string>();      randomstringgenerator rsg = new randomstringgenerator();      private void push(){         string random = rsg.randomstringgenerator();         arraylist.add(random);     }  } 

"randomstringgenerator" method generates random string.

i want append random string @ end of arraylist, stack (hence name "push").

thank time!

here syntax, along other methods might find useful:

    //add end of list     stringlist.add(random);      //add beginning of list     stringlist.add(0,  random);      //replace element @ index 4 random     stringlist.set(4, random);      //remove element @ index 5     stringlist.remove(5);      //remove elements list     stringlist.clear();
