First comes a line that shows which age group the information applies to. This is followed by a row with information on the number of men in that age group, followed by a row with the number of women in that age group. In total, the file contains information for the age groups 0 to 105 and the information about each age group extends over three lines as shown. The rows with information about the number of men and women are formatted using one or more spaces.

- Java programming This problem set will test your knowledge of System I/O, and variable assignment. Your task is to create several different java classes (.java files) that will produce a specific output based on the user input. All input will be given to you either as a command-line argument or typed in from the keyboard. Below you will find directions for each class you need to create. Please make sure that the class name and java file name match the name 1, ContainsAnyCase This program will accept two user inputted values that are strings. The first user input will be a single word the second user input will be a sentence of random words. This program should print "true" if the first word is in the sentence of words regardless of the casing. In other words case is ignored when checking if the word is within the sentence. The last string that this program should print is "true" or "false", nothing else. 2 PrintMathResult Write an application that will wait for three user inputted…arrow_forwardwrite a java program the can be used to create a file, move the file into another folder and rename the filearrow_forwardCreate a program named FileComparison that compares two files.
