In Java use the fork command to implement the following. Write a program (we’ll refer to this process as P) that uses the fork command to create a child process. The child (we’ll refer to this process as Process C) process shall create a child process (we’ll refer to this process as process GC). The P (parent) process shall print its PID along with the string “I am the grandparent process”. The C (child) process shall print its PID, and the string “I am the parent process”. The GC (grandchild) process shall print its PID and the string “I am a grandchild process

(From the topic API) Write a program that calls fork(). Before calling fork(), have the main process access a variable (e.g., x) and set its value to something (e.g., 100). What value is the variable in the child process? What happens to the variable when both the child and parent change the value of x? Write out the code for your program. Run the program and show your result. What value is the variable in the child process? What happens to the variable when both the child and parent change the value of x?

Suppose we execute the following code. int main() { fork(); printf("hello"); fork(); printf("hello"); } Suppose then, all calls to fork() were successful. How many instances of "hello" would you expect to see printed to standard output? Enter your answer as an integer.
Write a program called minishell that creates two child processes: one to execute 'cat minishell.c' and the other to execute 'grep main'. After the forks, the original parent process waits for both child processes to finish before it terminates. The standard output of 'cat' process should be piped to the input of the 'grep' process. Make sure you close the unnecessary open files for the three processes. Use fork.c, myls.c, myshell.c, pipes.c as examples Your program should be very similar to pipes.c
Using JavaFX, create a simple calculator application, like the following: The operators is ( + : " addition process" , -:subtraction process", *:"multiplication process" , /:"division process" , C : "Clear" , H: "History"); Validate that the first number and second is a numeric value if it is not throwing an exception. When clicking the operators (+, -, *, /): the result will display at the bottom, and stored in history. When clicking C, clear the first, second number and the history. When clicking H, the history will display at the bottom. When the user click / and the second number is 0 throw an arithmetic exception.

In java, there are four types of concurrency control, semaphores, monitors, locks and atomic values, give an example of when you would use one over the other, (you don’t have to provide code, just explain the situation).
The following program uses Pthreads to create two threads. They do some work for the process and then exit. The process then outputs a result. Assume all supporting libraries and other functions have been included. => Use the answer text field to describe what work (operations) the threads are doing, and what kind of result (what is it?) is output by the process. #include <pthread.h> #include <stdio.h> #include <stdlib.h> int res1, res2, a[100], b[100]; void *runner1(void *param); void *runner2(void *param); void readData(int []); int main(int argc, char *argv[]) { pthread_t tid1, tid2; pthread_attr_t attr; readData(a); readData(b); pthread_attr_init(&attr); pthread_create(&tid1, &attr, runner1, argv[1]); pthread_create(&tid2, &attr, runner2, argv[1]); pthread_join(tid1,NULL); pthread_join(tid2,NULL); printf("result = %d\n", res1+res2); } void *runner1(void *param) { int i, upper = atoi(param); res1 = 0; for (i = 0;…
