To return an arraylist, your method must include arraylist in the declaration, like so: public arraylist thisreturnsanarrlist (arraylist list) { return list; 'list' is of the type 'arraylist' } however, you can be more lenient and have a method return a list. since multiple classes inherit from list (i.e. arraylist and linkedlist ), you can. Here's how you can go about doing it. split the authors string you're getting as the method param based on the asterisk symbol. (using string.split(delim) method); the resultant string[] array needs to be iterated over using a for loop and each iterated element should be added to your list. The task is to get an integer from user (not 1 or negative number) and based on the number input (n), if it is even divide by 2, and if it is negative multiple n * 3 1. the method i must use is as follows: public static arraylist<integer> gethailstonesequence (int n) {. ^ this part is mandatory for my assignment, so it is necessary for me. You only have one list in the squad class, so you only have the one possible list to return. also your statement "check if such method exists" makes no sense in relation to the rest of your question. perhaps you should look up what the term "method" means in the context of a java application. in general your question makes no sense as currently.

Java Get Item Name From Arraylist And Compare Stack

This is my code for the quicksort test, but it always out of boundary, i try to debug but i do not where i did wrong. when they run the test for the list 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, it go out o. Stack implementation using array list. this is an arraylist implementation of a stack, where size is not a problem we can extend the stack as much as we want. let's write a program to demonstrate implementation of stack using arraylist. import java.util.arraylist ; import java.util.list ; ** * this is an arraylist implementation of stack. This stack frame holds parameters of the invoked method, mostly the local variables and the return address of the method. the creation of these stack frames will be iterative and will be stopped only when the end of the method invokes is found in the nested methods.
