- Do not use Swing for the console output--the console output must be displayed in the console. Write the following code in Java. Using classes of the Java Collections Framework, write a program that allows the user to specify a text file, open the file, and print a two-column table consisting of all the words in the file together with the number of times that each word appears. Words are space-delimited and case-sensitive. The table should appear in the console (do NOT use Swing/JTable) and list the words in alphabetical order. Implement try/catch blocks for cases where the file cannot be opened.JAVA PPROGRAM Please Modify this program with further modifications as listed below: ALSO, take out and change the following in the program: System.out.println("Program terminated."); because the test case does not need it And change this in the program: Please enter the file name or type QUIT to exit:\n so it reperats once for every test case because it repeats twice in every case as shown in the screenshot. I only need it once. I have provided the failed the test cases and the inputs as a screenshot. The program must pass the test case when uploaded to Hypergrade. import java.io.*;import java.util.ArrayList;import java.util.Scanner;public class SymmetricalNameMatcher { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); String fileName; do { // Prompt the user to enter a file name or 'QUIT' to exit.

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…
- For this assignment, your program will read characters from a string for the purpose of assigning data from that string to the private data members of a class. This simulates a program that would read a record in from a stored file into memory for the purpose of making changes to that record. Below is a template of your program. For this assignment, you MUST use loops (100 pts off if not using loops) and you cannot use the following methods: indexOf() substring() subsequence().I need help with making a Java program, the general class that will be called “Businesses”. This class must have the following methods: selectSalesTax() – This method will read in a file “stateTaxInfo.txt” that has the name of a state and the tax percentage (decimal form) for that state and save them to the given arrays. It will then print a menu for the user to choose the state that the business is in and set the variables to hold the values. getCustomerName() – This method will prompt the user for the name of the person using the program calcSalesTax() – This method will be sent a subtotal and calculate the sales tax outputReceipt() – This method will output a generic receipt as follows: Subtotal $37.50 Sales Tax $2.44 Total $39.94 outputMenu() - This…I am trying to figure out why the sum at the end of my Java code is not working correctly.

- Program to compute interest = p * r * t, where p = $10K, rate = 6%, t = 10 years; these values are to be passed from main() Besides main() the program has two methods: one that computes the interest and on that rounds interest to two decimal places public class DisplayInterest public static void main(String[] args) call a method that will do the computation with values for the above variables; with the exception of year, they are double main() displays computed interest after rounding computation method() rounding method() Note:- Please type and execute this java program and also need an output for this java program.java a. A method named contains exists that takes an array of Strings and a single String, in that order, as arguments and returns a boolean value that is true if the array contains the given String. Assume that an array of Strings named names is already declared and initialized. Call the method to see if the array contains the name "Fred", and save the result in a new variable named fredIsHere. b. Given a method named printMessage that takes a String argument and returns nothing, call the method to print out "I love Java!".
