If you want to create and populate a Java ArrayList with Java 9, 11, and newer, you can use this syntax:
List<> ints = ArrayList<Integer>(List.of(1,2,3));As shown, this uses the usual ArrayList constructor and the Java List.of method.Once you have an ArrayList like this you can continue to add new elements to it as usual:
ints.add(4);
