After all of the text files in the directory have been read, the output of the program should display the permutations in sorted order along with the original term. Use the dollar sign as the end of term symbol.

- Make a telephone lookup program. Read a data set of 1,000 names and telephone numbers from a file that contains the numbers in random order. Handle lookups by name and also reverse lookups by phone number. Use a binary search for both lookups. This assignment needs a resource class and a driver class. The resource class and the driver class will be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code. The code needs to be written in Java.

- In Java: -Using a BST Interface (Binary Search Tree) -Create a class Disk. Disk contains four fields: model (String), size (int), measure (String, for GB or TB), and performance index (int). -Disk needs a constructor to initialize all fields, a toString method, and an equals. Make the class Comparable and write a compareTo method that compares Disks based on the size of the disk. Make sure your comparison accounts for the fact that some numbers are in GB and some are in TB. Write a method that will return true if the disk is the same size as the parms; parms are the size and measure("GB" or "TB"). Also write a method to create a Comparator which compares Disks based on the performance rating. -The client code should do the following: Write a function called build, which will open the disks.txt file, read in each disk and add it to the BST. For each disk the model is on the first line, and the second line contains the size, measure, and performance index. The BST is passed to build as…WHAT IS THE RELATION OF METASTABILITY TO MEMORY ELEMENTS? OWN ANSWER PLEASE. THANK YOU. ILL UPVOTE.
