Encapsulation is one of the fundamental concepts in object-oriented programming. It is also often used to hide the internal representa state of an object from outside. This is called information hiding. By using the data in Figure 1, show your investigation if hacker approach to gain access to the code of your bank account. class Account { private int acount_number; private int account_balance; public void show Data() { I/ code to show data public void deposit(int a) { if (a < 0) { I/show error } else account_balance = account_balance + a; Figure 1: Account class

Write a class for the following object. Fraction - an object that represents parts of a whole number. A fraction is created by supplying a numerator and a denominator. Instance related actions 1. add - mutates this fraction by adding the other fraction value 2. subtract - mutates this fraction by subtracting the other fraction value 3. multiply - mutates this fraction by multiplying with the other fraction value 4. divide - mutates this fraction by dividing by the other fraction value 5. tostring - represents the fraction in a form of 'numerator/denominator" 6. compareTo - returns the following values 1. O when this fraction is equal with the other fraction 2. 1 when this fraction is greater than the other fraction 3. -1 when this fraction is less than the other fraction Example fraction1 = 1/2 fraction2 = 3/4 When fraction1.add(fraction2] is called, it will make the value of fraction 1 as 5/4. When fraction1.subtract(fraction2) is called, it will make the value of fraction 1 as -1/4.…

Please help me solve it today I posted it yesterday and got rejected I don't know why:( Please help me solve this with Java Game class instructions:• Game class has three attributes: points (which represent the number of points awarded when winning the game), status (false if the game has not been played and true if the game has been played), and description (which is a text description of the game). Note that description attribute is a read-only variable. • In the constructor, initialize points to zero, status to false, and description to the given parameter.• isPlayed method returns true if the game has been played, and false otherwise.• getPoints is a getter method for points attribute.• play method is an abstract method.• Override toString method to return the game description.• Override equals method so that two games are the same if their descriptions are the same. :instructions class ) HangMan• HangMan is a game in which a player tries to guess a word based on a given hint.…
