Question

Good Morning Chegg. I have some more Java coding questions I would like an answer to. Please full codes only and try as many as you can. None of these are homework, just practise for me. If you only feel like doing a few, problems: 44, 50, 56, 58 are the main problems. Thank you in advance

44. In Internet programming, programmers receive parameters via a query string, which looks like a String with fields separated by the "&" character. Each field typically has a metadata part and a data part separated by the equal sign. An example of a query string is:

first=Mike&last=Jones&id=mikel&password=hello

Using Scanner at least once, parse a query string and output each field on a different line after replacing the equal sign with a colon followed by a space. For example, for the preceding sample query string, the output should be:

first: Mike
last: Jones
id: mikel
password: hello

50. Often websites display the visitor count ("You are visit or number 5246"). Write a program that reads a file that holds the visitor count, outputs it. and updates the file, incrementing the visitor count by 1.

53. We are interested in checking the number of times a given word (for example. the word secret) appears in a file. You should assume that lines do not wrap, that is, a line does not continue on the next line. Warning: You could have letters arranged like secsecret. Design a class that encapsulates that idea. Test it with a client program.

54. Design a class that checks if the contents of two text files are identical and, if not, determines how many lines are different. Lines are different if they differ in one or more characters. Test your class with a client program.

56. The most common characters in an HTML file are < and >. Every < must be followed eventually by a > character before the next < character is found. There should be an equal number of both in the file. Design a class that encapsulates that idea. Test your class with a client program.

58. Incryptograms, each character is encoded into another. If the text is long enough, one can, as a strategy, use the frequency of occurrence of each character. The most frequently occurring character will likely be the code for an e, because e is the most frequently used letter of the English alphabet. Design a class that attempts to determine the relative frequency of each letter by reading a file and keeping track of the number of times each of the 26 English alphabet characters appears. Also provide methods. such as highestFrequencyCharacter and lowestFrequencyCharader. Test your class with a client program. **
