The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly. You also will use a file named DebugEmployeeIDException.java with the DebugTwelve4.java file. // An employee ID can't be more than 999 // Keep executing until user enters four valid employee IDs // This program throws a FixDebugEmployeeIDException import java.util.*; public class DebugTwelve4 { public static void main(String[] args) { Scanner input = new Scanner(System.in); String inStr, outString = ""; final int MAX = 999; int[] emps = new int[4]; for(int x = 0; x < emps.length; ++x) { System.out.println("Enter employee ID number"); inStr = input.next(); try { emps[x] = Integer.parseInt(inStr); if(emps[x] > MAX) { throw(new…
OverviewYou should enter this task, ask the user for a word and then search for a file to see if that word is among the words in the file. Task Write a java programThis exercise comes with three text files named wordlist1.txt, wordlist2.txt and wordlist3.txt. These files contain a large amount of words in English. Each file contains more and more words. Each word in these files is on a separate line and the words contain only lowercase letters. Your task is to write a program that reads all these words from the file and checks if a keyword, which the user entered, is among the entered words. The program should also count the total number of words contained in the file used. The program should measure how long it takes to complete the search, ie how long it takes to read all the words and check if the keyword is among the words or not. The program should start by asking the user for the word to be searched for. Then the words in the file should be counted and compared if the keyword…
Create a simple java program that reads all the content in a .txt file, the user will enter the filename to be opened. In this case, the file will contain multiple lines of student details with each line containing a single student detail. Your task is to then create a student class that models the firstname, lastname, year of birth and gender of every student. The student class should further be able to assign every student created with a student number using a class variable[format is 2022000X, X is a number such as 1,2..] and be able to calculate the age of each student. Within the driver class add all the students read from file into an ArrayList and then print the first and last student in the list. You are additionally expected to deal with most common exceptions

*with psuedo code First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "WeightedAvgDataAnalyzer" (without the quotation marks), that does the following: This program is similar to the previous assignment - "WeightedAvgDropSmallest" - with a major difference that the inputs for the program will be read from a file and the output for this assignment should be written to a new file. The concept of application is as follows: The program will read numbers from a file - data.txt - that you will create, where the weight is a double (greater than 0.0 and less than or equal to 1.0) and the other numbers are the number, n, of lowest values to drop and then the numbers to be averaged after dropping the lowest n values. Example data.txt file would display: 0.5 3 10 70 90 80 20 The program then calculates the weighted average of all those numbers except the lowest n numbers, where…
