*Not in C++ Language! Pleaseeee in Java?!!*

Programming Exercise 3.20 required you to design a PID manager that allocated a unique process
identifier to each process. Exercise 4.20 required you to modify your solution to Exercise 3.20 by writing
a program that created a number of threads that requested and released process identifiers. Now
modify your solution to Exercise 4.20 by ensuring that the data structure used to represent the
availability of process identifiers is safe from race conditions. Use Pthreads mutex locks.

if there is any questions, leave a comment. Thank you.

Programming Language Required: C Write a multithreaded program in C (not c++) using the pthread library and dynamic memory(malloc) that multiplies two matrices together. The numbers in the matrices must be read in from a text file. The program should also check if the two matrices are capable of being multiplied together. The amount of threads used has to be dynamic. The user should be able to choose how many threads they wish to use using the command line. Finally,...

THIS QUESTION IS BASED UPON JAVA PROGRAMMING. Exercise 1 In this exercise, you will add a method swapNodes to SinglyLinkedList class. This method should swap two nodes node1 and node2 (and not just their contents) given references only to node1 and node2. The new method should check if node1 and node2 are the same nodes, etc. Write the main method to test the swapNodes method. Hint: You may need to traverse the list. Exercise 2 In this exercise, you will...

Programming Language: JAVA In this assignment you will be sorting an array of numbers using the bubble sort algorithm. You must be able to sort both integers and doubles, and to do this you must overload a method. Bubble sort work by repeatedly going over the array, and when 2 numbers are found to be out of order, you swap those two numbers. This can be done by looping until there are no more swaps being made, or using a...
