1. Write a class Compare3 that provides a static method largest. Method largest should take three Comparable parametersand return the largest of the three (so its return type will also be Comparable). Recall that method compareTo is part ofthe Comparable interface, so largest can use the compareTo method of its parameters to compare them.
2. Write a class Comparisons whose main method tests your largest method above.
• First prompt the user for and read in three strings, use your largest method to find the largest of the three strings, andprint it out. (It’s easiest to put the call to largest directly in the call to println.) Note that since largest is a staticmethod, you will call it through its class name, e.g., Compare3.largest(val1, val2, val3).
• Add code to also prompt the user for three integers and try to use your largest method to find the largest of the threeintegers. Does this work? If it does, it’s thanks to autoboxing, which is Java 1.5’s automatic conversion of ints toIntegers. You may have to use the -source 1.5 compiler option for this to work.

Hi, Please find my implementation.

Please let me know in case of any issue.

import java.util.Scanner;

public class Comparisons {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Enter three integes: ");

int val1 = sc.nextInt();

int val2 = sc.nextInt();

int val3 = sc.nextInt();

System.out.println("Largest: "+Compare3.largest(val1, val2, val3));

}

class Compare3{

public static Comparable largest( Comparable val1, Comparable val2, Comparable val3){

// getting largest between val1 and val2

Comparable largest = val1.compareTo(val2) > 0 ? val1 : val2;

// getting largest between val1, val2, val3

largest = largest.compareTo(val3) > 0 ? largest : val3;

return largest;

}

/*

Sample run:

Enter three integes: 89 23 90

Largest: 90

Make a public class Creater that provides a single class (static) method named subtractor. subtractor takes a single int argument and returns a method that implements the following Create interface: public interface Create { int change(int something); --------------------------------------------------------------------- The returned “function” should implement Create so that it subtracts the value passed to subtractor. For example Create one = Creater.substractor(5); Create two = Creater.subtractor(-3); System.out.println(one.change(5)); // should print 0 System.out.println(second.change(3); // should print -6 The answer should be is a single...

for java!! Make a public class Value that provides a static method named test. test takes a single int argument and returns an anonymous object that implements the following Absolute interface: public interface Absolute { int same(); int opposite(); } -------------------------------------------------------------------------- The returned object should implement same so that it returns the passed int as it is, and opposite so that it returns the passed int as the int * -1. For example Absolute first = Value.test(-90) Absolute second =...

Java Programming Using the class below, please ), write a static method called parse that parses a String for balanced parentheses. we seek only to determine that the symbol ‘{‘ is balanced with ‘}’. parse accepts a single String parameter and returns an int. If parse returns a minus 1, then there are no errors, otherwise, parse should return the position within the String where an error occurred. For example parse(“{3 + {4/2} }”) would return -1 parse(“{ { 4*X}”)...
