The important points about java collections class are: java collection class supports the polymorphic algorithms that operate on collections. java collection class throws a nullpointerexception if the collections or class objects provided to them are null. collections class declaration. let's see the declaration for java.util.collections class. It contains polymorphic algorithms that operate on collections, "wrappers", which return a new collection backed by a specified collection. the methods of this class all throw a nullpointerexception if the collections or class objects provided to them are null. class declaration. following is the declaration for java.util.collections class −. Collections class is a member of the java collections framework.the java.util package is the package that contains the collections class. collections class is basically used with the static methods that operate on the collections or return the collection. Collection classes should clearly specify in their documentation any restrictions on what elements may be added. if a collection refuses to add a particular element for any reason other than that it already contains the element, it must throw an exception (rather than returning false). this preserves the invariant that a collection always. The constructor for each collection class, except struct, takes in a parameter value that is an element of the types system enum. the collection instance can store items of that type only. the types::anytype enum element is a special case and it cannot be used to construct a usable collection object, such as a set object.

Table 1 lists the supported collection classes and cursor types for cursor c functions that can only be used with cursors. an x indicates support for that class or cursor type. the following key lists the collection class names and cursor types. The collection interface (java.util.collection) and map interface (java.util.map) are the two main “root” interfaces of java collection classes. what is a framework? a framework is a set of classes and interfaces which provide a ready made architecture. in order to implement a new feature or a class, there is no need to define a framework. The collection class will allow us to have access to each button as well as that button’s properties and functions (e.g status , x and y position, color). ok lets get coding. the code. the code for the collection class is fairly simple. if you understand how pointers, classes, templates and the operator works, then you are already 90% there.
