am working on code for a chained symbol table that will be part of a semantic checker. I have the basic outline of the code, but I am unsure what to put inside the functions to actually implement them. I have a list of the regular expression that will be used in this semantic checker, but I am wondering how to implement the rest of the code for the chained symbol table so that all regular expression symbols will be accounted for.

write a program to create a thread "A", which creates two child threads "B" and "C"."A" must terminates after both "B" anc "C" have terminated."B" and "C" must print their awn names 100 times and then terminate

Discuss the concept of parameters. What are parameters for? What is the difference between formal parameters and actual parameters? Give an example in Java code that illustrates formal parameters and actual parameters.

Write a program to take an order for a computer system. The basic system costs 375.99. the user then has to choose from a 38 cm screen(costing 75.99) or a 43 cm screen (costing 99.99).the following extras are optional.

Item price
Antivirüs software 65.99
printer 125.00
The program should allow the user to select from these extras and then display the final cost of the order.
