Set items: 1 2 3 4 Cloned Set items: 1 2 3 4 Explanation In the above program, we imported the "java.util.*" package to use theHashSetcollection. Here, we created a public classMainthat contains amain()method. Themain()method is the entry point for the program. And, we created ...
In Java, theArrayList clone()method creates a shallow copy of the list in which only object references are copied. If we change the object state of a list item inside the firstArrayList,the changed object state will also be reflected in the cloned list. ...
