copy arraylist java
List<Something> original=new ArrayList<>();
//insert elements
List<Something> copy=new ArrayList<>(original);//create copy here
System.out.println(copy.equals(original));//true because the copy has the same elements
System.out.println(copy==original);//false because it is another Listcopy arraylist to another arraylist java
You can use such trick:
myObject = new ArrayList<Object>(myTempObject);
or use
myObject = (ArrayList<Object>)myTempObject.clone();
You can get some information about clone() method here
But you should remember, that all these ways will give you a copy of your List, not all of its elements. So if you change one of the elements in your copied List, it will also be changed in your original List.Copyright © 2021 Codeinu
