===Generic methods and constructors=== Usage of generics may be limited to some particular methods, this concept applies to constructors as well. To declare a parameterized method, type variables are written before the return type of the method in the same format as for the generic classes. In the case of constructor, type variables are declared before the constructor name. <syntaxhighlight lang="java"> class Mapper { // The class itself is not generic, the constructor is <T, V> Mapper(T array, V item) { } } /* This method will accept only arrays of the same type as the searched item type or its subtype*/ static <T, V extends T> boolean contains(T item, V[] arr) { for (T currentItem : arr) { if (item.equals(currentItem)) { return true; } } return false; } </syntaxhighlight>
