Copies all of the elements from one list into another. After the operation, the index of each copied element in the destination list will be identical to its index in the source list. The destination list must be at least as long as the source list. If it is longer, the remaining eleme...
Changing the Parent property simply moves a control from one tab page to another. Which probably explains why the views look the same. You've already got code that creates controls for the first page. Run that code again to create another set of controls. If this is designer-generated ...

we can easily achieve this operation. ThesubListmethod allows us to extract a portion of a list, while theaddAllmethod allows us to add all elements from one list to another. By combining these methods, we can create a new list that contains a range of elements copied from another list....
Copy value to a List static<T> void copy(List<? super T> dest, List<? extends T> src) Copies all of the elements from one list into another. importjava.util.Arrays;importjava.util.Collections;importjava.util.List;publicclassMain {publicstaticvoidmain(String args[])throwsException { List...
If you want a deep copy (the elements also copied) you are going to have to handle each element separately for(MyObject obj:buffer){ b1.add(obj.clone()); b2.add(obj.clone()); } TheCollections.copy(...)javadocsays this: "Copies all of the elements from one list into another. Afte...
Another approach to copy a list is to use theaddAll()method provided by theCollectioninterface. This method allows us to add all the elements from one list to another. importjava.util.ArrayList;importjava.util.List;publicclassCopyListExample{publicstaticvoidmain(String[]args){List<Integer>origina...
List<SomeBean> newList = new ArrayList<SomeBean>(otherList); Note: still not thread safe, if you modify otherList from another thread, then you may want to make that otherList (and even newList) a CopyOnWriteArrayList, for instance -- or use a lock primitive, such as ReentrantReadWrite...
As I step through the code I notice that the structure and the elements are copied to this new object, more than the language agnostic structure only. In Java, what is a shallow copy? How does it differ from a Java deep copy (if that exists)? java clone shallow-copy Share Improve ...
