Consider the Java code below. We have already fleshed out a loop invariant for you. Your task is tofill in the missing Hoare logic justifications so that we have a proof that mult returns the product of xand y. You may be inspired by worked examples from class.// precondition: x >= 0 && y >= 0;int mult(int x, int y) {int kx, n =while (k = 0)if (k%2k /= 2;==y, res = 0;{ // @loop_invariant x1) res = res + n;B*yknres;n = 2;}return res%;B}// post-condition: returns x y*

1. Precondition:The function starts with:x >= 0 && y >= 0 This ensures that the…

In Java: The program extends the representation for rational numbers Add a test class TestSimplifiedRational Define the simplified rationals r1..r4 and initialize them with 1/2, -3/9, 10/12 and 1 Compute sum=r1+r2 and diff=r4-r3 Simplify both results Check if they are equal, using equals and comparing their numerators and denominators. What do you observe? Compare r1 with r2, r3 and r4. Print all the rational numbers and partial results.
This is a debugging question - The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly.

Java problem implement this specification. In addition, while Scanner input and System.out output will take place only in the main method, all solitaire game simulation and computation of the first player win probability estimate should take place in a method getAdvantage that takes an integer parameter for the number of games to simulate, and returns a double-precision floating-point first player win probability. The main method will read the desired number of simulations, call method getAdvantage with that number, and report the returned number in the specified format. Specification: First-Player Advantage Pig is a folk jeopardy dice game with simple rules: Two players race to reach 100 points. Each turn, a player repeatedly rolls a die until either a 1 ("pig") is rolled or the player holds and scores the sum of the rolls (i.e. the turn total). At any time during a player's turn, the player is faced with two decisions: roll - If the player rolls a 1: the player scores nothing…
in java could you showme how to build the UML diagrams, i have more to add to this but just confusedon how this all works together
Give me all the answers in Java. Don't try to copy other's work otherwise I'll give you multiple dislikes. Others are wrong so don't copy.
Pls help on this questions ASAP
Implement all the classes using Java programming language from the given UML Class diagram. Note: This problem requires you to submit only one class: Date.java. Do NOT include "public static void main()" method inside all of these classes. The class would be tested, using the unit-testing framework JUnit 4.
WRITE A JAVA PROGRAM Methods can be used to define reusable code and organize and simplify code. Problem:- Suppose that you need to find the sum of integers from 5 to 15, from 16 to 30, and from 31 to 39, respectively. Define a public static sum method that take two int parameters -> (int start, int end) In the method, use for loop to add all the number from start to end. Later, invoke the sum inside the main method. Do the sum for each a) 5 to 15; b) 16 to 30; and c) 31 to 39 separately and later print the results. Output: Sum from 5 to 15 is 110 Sum from 16 to 30 is 345 Sum from 31 to 39 is 315
In this work, we ask you to design a deterministic Finite Automaton (FA) to recognise arithmetic expressions. When we say arithmetic expression, we mean a kind of expression you can type in a very basic desk calculator. That is, neither variables nor brackets are allowed. It contains only numbers and four arithmetic operators, +, -, *, and /. The following are some examples of arithmetic expression: 1. Any number string with or without signs - e.g. 3, -1, +10, 3.14, -0.70 and 099. 2. Number strings mixed with arithmetic operators e.g. 3+5, -1+2*3, 7/10-0.7, and -1.4-+8.2. An example of FA diagram for recognising a non- negative integer is given below. You may use it as a start point. You need to add a few more states and transitions to handle numbers with decimal point and signs (e.g. -5, +2, 0.21, -32.6, +99.05, but not the form 1.0E-3). Most importantly, you also need to add a few more things to deal with the arithmetic operators +, -, *, /. →start 0-9 digit 0-9
In Java, implement abstract classes and interface in the grading system. Include three different implementation methods in solving the grade. Kindly follow the example of coding below (abstract class should be included): Example: Enter Prelim: 30 Enter Midterm: 30 Enter Endterm: 40 --------------------- Formula: (Prelim+ Midterm + Endterm)/3 ------------------------------
