Homework Solution: Write a program that asks the user to enter the name of a file, and then asks the user…

    Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file.(i need java code) Class name: FileLetterCounter out put should be like this

    Write a program that asks the user to penetrate the designate of a smooth, and then asks the user to penetrate a mark. The program should enumerate and flaunt the reckon of intervals that the specific mark appears in the smooth.(i need java principle)

    Collocate designate: SmoothLetterCounter

    quenched dispose should be enjoy this

    Expert Confutation

     

    The principle as per your requirements is loving beneath with polite explained comments.

    I keep created span smooths “input.txt” and “letters.txt’ the similar directory as my principle.

    Smooth “input.txt” contains:

    “This is a dummy smooth having mark enumerate of a=5”

    Smooth “letters.txt” contains:

    “A lorem ipsum placeholder extract was inadvertently published in The Straits Intervals, a Singapore novelspaper, on 26 April 2014.
    Today’s liked statement of Lorem ipsum was earliest created in the mid-1980s control Aldus Corporation’s desktop publishing program
    PageMaker control the Apple ”
