- PS: Please answer number 1 and 2 as they are related everything altogether. Make sure the code delivers expected successful output. 1. Create a Java class named Package that contains the following:a. Package should have three private instance variables of type double named length, width, andheight.b. Package should have one private instance variable of the type Scanner named input, initializedto System.in.c. No-args (explicit default) public constructor, which initializes all three double instance variables to1.0.d. Initial (parameterized) public constructor, which defines three parameters of type double,named length, width, and height, which are used to initialize the instance variables of same name.e. Public copy constructor, with a parameter of type Package, used to duplicate anexisting Package object.f. Three public void methods named inputLength, inputWidth, and inputHeight. Each methodwill prompt the user for the appropriate property, and input a double value usingthe Scanner…s a simple program where we could identify the fields on the web page easilyusing just the class attribute. There are others that are more complex, and the fieldcan be identified by alternative attributes. Some of these attributes are the id, the tagname, etc. These have not been covered here, but you are likely to need them whenyou deal with more complex web pages—google is probably one of the simplest bydesign, since it is a universal search application where most of its complexity resideson the server end.Write The code for this algorithm?Design and implement a class called BankAccount. A BankAccount has ID, owner(Client Name) balanceInJD(double), balanseInNIS(double), exchange rate(static attribute) and branch(city), Define the BankAccount constructor(s) to initialize these fields. Define getter and setter methods for all instance data fields. Define withdraw, deposit, transferIN (transfer between Balances on the same account), transferOut(transfer between Balances on different accounts) methods and override the toString() method that returns a one-line description of the BankAccount. Note: 1. client A can transfer from his balanceInJD to his balanceinNIS or vice versa. 2. client A can transfer from his balanceInJD or his balanceInNIS to client B balanceinNIS or balanceInJD. 3. Use exchange rate when transferring between balances in different currencies.
