Define a class named ComparableNames thats extends Person and
implements comparable
Define a class named ComparableNames that extends Person (defined below) and implements Comparable. Override the compare To method to compare the person on the basis of name. Write a test class to find the order of two ComparableNames. class Person String name; Person00 Person(String n) name=n: Hint: in class ComparableName, you only need a constructor with arg to initialize the data filed defined in the super class...
Consider the following Java 8 code, and select true statements: public interface Functionlnterface1 void abstFun1 (int x) public interface Functioninterface2( void abstFun2(int x); public class Main implements Functioninterface2( @Override public void abstFun2(int x) System.out.printin(3'x); public static void main(Stringl args) ( Functioninterface1 fobj (int x)->System.out.printin(2"x) fobj.abstFun1(5); Main me - new Main; me.abstFun2(5); Functioninterface2 fobj2-(int x)->System.out.printin(4%; fobj2.abstFun2(5) 2 in main will not run because abstFun2 was previoudly implemented. O The fobj instance of Functionlnterface1 is created using the lambda at runtime without...

Implement the classes in the following class diagram. The Book class implements the Comparable interface. Use implements Comparable<Book> in the class definition. Now, all book objects are instances of the java.lang.Comparable interface. Write a test program that creates an array of ten books. 1. Use Arrays.sort( Book[]l books) from the java.util package to sort the array. The order of objects in the array is determined using compareTo...) method. 2. Write a method that returns the most expensive book in the...

In java, create class BNode(T), which implements the interface TreeNode(T) interface methods: void setRight(TreeNode(T) right) - sets right side of node, where right is the node to the right of this node void setRight(TreeNode(T) left) - sets left side of node, where left is the node to the left of this node TreeNode getRight() - gets the right node TreeNode getLeft() - gets the left node T getData() - gets the data within the node THEN, create class BT(E), which...
Define a DNA class: Please consider the features of Java classes, and then define a Java class for a DNA sequence object to include instance variable names and methods that you can use to define a piece of DNA sequence. You can use a UML (Universal Modeling Language) diagram to define your class, or you can simply list the variable, and method's names, data type, and parameters the methods will take in.
