- Is there a limit to how many parameters a catch block may have?Create the Singly Linked List after having executed the following methods. Each item must have a headand tailreference. Whenever a method is not expected or invalid, write Exception.

Below arethe details needed for the different methods:a. The default constructor will assign the client a default name (any value ofyour choice). Keep in mind that a single mailbox (e.g., gmail) can handle amaximum of 15 emails, but it can hold less, which is the actual size of theemails array. So, the constructor should instantiate the emails arrayinstance variable by creating an array of size 15. It should also set theactualSize variable to 0.b. The MailBox (String client) constructor should call the default constructorusing chaining. It should then initialize the client variable using the clientparameter.c. The toString method…
- Create the Singly Linked List after having executed the following methods. Each item must have a headand tailreference. Whenever a method is not expected or invalid, write Exception. Only the process not the code •addTail("Bungee")•addTail("Yeti")•addTail("Screendoor")•addTail("Ladder")•removeHead()•addHead("Flag")•addHead("Ducky Tube")•addHead("Snorkel")In Java programming Write the code to print out a customer report. Your code must read each customer from a file, populate the object, place the object in a linked list, and display the data from the linked list. Use the customer object name from Customer customer = new Customer ( “ customer name” ); Assume you have opened a file and read a line into the customer object. Write the signature line for this method Write the line of code that will write the object to a linked list Write the line of code that will print the customer object properties. Be sure to include a textual description of each property.Write a Java program that asks the user to enter items until the user chooses to stop, stores them into links (nodes), and chains the links together into a linked list. You will need to make the following changes: Your linked list should store information about Customers' Transactions that contain three fields: customer name (string), customer number (int), and transaction description (string). Instead of putting all of your code inside the main source code file, you should create the following functions: o addToStart(Item x) o addToEnd(Itemn x) o insertAt(Item x, int n) o remove(int customer number) o reverse() o printList() • Instead of simply asking the user if they want to add a new link, your main program should offer the user a menu of options: o Add a new link to the end o Add a new link to the beginning o Insert an element at index n into the list. 0 Remove a link from the list o Reverse the list o print out the entire list o Quit the program

You are asked to implement a trigger which needs to take following into consideration: a. The trigger needs to be fired after a new row has been inserted into table Orders, or after a row has been deleted from table Orders which indicates an order has been cancelledb. Each order may contain multiple books in ORDERTITEMS table You also need to write SQL statement or/and PL/SQL code to demonstrate that the implemented trigger accomplishes the business logicthis is for javaScriptDisplay "bad request" if the response's status is 400.

All the IDs are unique. What I want to do is I want to read from the text file and then sort the Id in order then put it back into the text file. How can I do this in java? Can you write a code for it in java. For example: the text file text.txt contains Id Name 3 Kark 1 Mia 5 Tyrus 2 John After sort, the text.txt will be 1 Mia 2 John 3 Karl 5 Tyrus
