Write a generic class that stores two elements of the same type and can tell the user which one is the larger between the two. The type of the two elements should be parameterized and the class should have a function called “maxElement” that returns the larger element.
write this java code
Java:
Code a generic class called Location that describes a point in the xy plane. The Location class requires instances variables to represent the x and y coordinates, a parameterized constructor, one method to change both coordinates of the point (both x and y), getX and getY methods and a toString. These are the only methods in this class. The class uses a generic type so that any numeric value can be used for the coordinates (2 integers, 2 floats, 2 doubles, etc) or 2 Strings (for example three and ten).
Write a code segment in main( ) to thoroughly test the class Location. Your code segment should create two locations, one represented by a pair of real numbers and one represented by a pair of Strings.
If you have a generic class :
public class Search<A, B>
how can you find all the occurences of B in the search

- This one in c++.arrow_forwardA) Write a generic Java queue class (a plain queue, not a priority queue). Then, call it GenericQueue, because the JDK already has an interface called Queue. This class must be able to create a queue of objects of any reference type. Consider the GenericStack class shown below for some hints. Like the Stack class below, the GenericQueue should use an underlying ArrayList<E>. Write these methods and any others you find useful: enqueue() adds an E to the queue peek() returns a reference to the object that has been in the queue the longest, without removing it from the queue dequeue() returns the E that has been in the queue the longest, and removes it from the queue contains(T t) returns true if the queue contains at least one object that is equal to t *in the sense that calling .equals() on the object with t the parameter returns true.* Otherwise contains returns false. size() and isEmpty() are obvious.arrow_forwardConsider a declaration of a generic method compute: public static > void compute(T[] data) { ... } Which statement is true about a parameter supplied when calling this method? The parameter can be any array holding elements of some class C, as long as C is the parent of a class that implements the Comparable interface. The parameter can be any array holding elements of some class C, as long as the class C implements the Comparable interface. The parameter can be any array holding elements of some class C since it is a generic method. The parameter can be any array holding elements of some class C, as long as the class C implements the Comparable interface or C extends a class that implements Comparable.arrow_forward
