Implement a system of three concurrent processes which read and write sequence numbers to a file. Each of the three processes must obtain 200 integers from the file. The file only holds one integer at a given time. Given a file, F, containing a single integer, each process must perform the following steps: Please show steps and answer. 1. Open F 2. Read an integer N from the file 3. Close F 4. Output N and the process ID (PID) (either on the screen or an output file) 5. Increment N by 1 6. Open F 7. Write N to F (overwriting the current value in F) 8. Close F Will the numbers that are read by the processes always be unique? Or do you observe duplicates of numbers being obtained by different processes? That is, does a particular integer N appear in the output of more than one process? Rewrite your implementation of these 3 processes to guarantee that no duplicate numbers are ever obtained by the processes. In other words, each time the file is read by any process, that process reads a distinct integer. The processes must run concurrently. Briefly describe why the code sequence above can lead to duplication of integer values and discuss how your solution will avoid these duplicates.

Write a java program. The program asks for an input of the name of a txt file. Then creates a Multiplication Table from 1 to 9, and writes the table into the file. When you run your program, you may see the result like this: Problems @ Javadoc Declaration Console X Data Hierarchy Lab5Q1 [Java Application] C:\Program Files\Eclipse Foundation\bin\javaw. Enter a file name: table.txt output file has been created: table.txt When you open the file table.txt in the folder (it should be in the same folder as your java source file), you will see the file as follow: table.txt - Notepad File Edit Format View Help This is a Multiplication Table 1x1=1 1x2=2 2x2=4 1x3=3 2x3=6 3x3=9 1x4=4 2x4-8 3x4-12 4x4=16 1x5-5 2x5=10 3x5-15 4x5-20 5x5=25 1x6-6 2x6-12 3x6=18 4x6=24 5x6=30 6x6=36 1x7-7 2x7-14 3x7-21 4x7-28 5x7-35 6x7-42 7x7=49 1x8-8 2x8-16 3x8=24 4x8=32 5x8-40 6x8=48 7x8=56 8x8=64 1x9=9 2x9-18 3x9=27 4x9=36 5x9-45 6x9-54 7x9-63 8x9-72 9x9-81

Write a java program that will generate a permuterm index from the terms in the files in an input directory. The program should prompt the user for a single directory and find all of the terms (after processing) in each file in it. The program should then find the permutations of each term and store them (keeping track of the original word each permutation comes from). 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.
Java only Design, implement and test a Java class that processes a series of triangles. For this assignment, triangle data will be read from an input file and the program’s output will be written to another file. The output file will also include a summary of the data processed. You must use at least one dialog box in this program. The data for each triangle will be on a separate line of the input file, with the input data echoed and the results referred to by the line number (see example). On initialization, the program will prompt the user for both an input and an output file. If a non-existent input file is specified, the appropriate exception must be handled, resulting in an error message. For the exception case, re-prompt the user for the correct input file. Once the I/O file is specified, the program will read in and process all the entries in the file. The output of the program will be written to the specified output file and echoed to the console. The program will…
In this assignment, you will create a Java program to search recursively for files in a directory.• The program must take two command line parameters. First parameter is the folder to search for. Thesecond parameter is the filename to look for, which may only be a partial name.• If incorrect number of parameters are given, your program should print an error message and show thecorrect format.• Your program must search recursively in the given directory for the files whose name contains the givenfilename. Once a match is found, your program should print the full path of the file, followed by a newline.• You can implement everything in the main class. You need define a recursive method such as:public static search(File sourceFolder, String filename)For each subfolder in sourceFolder, you recursively call the method to search.• A sample run of the program may look like this://The following command line example searches any file with “Assignment” in its name%java FuAssign7.FuAssignment7…
