Question

i'm new to programming in this language and i have no ideawhat im doing. i completed c programming but my class onlyspent 2 days on c++ so i dont know alot of those techniques used.so i have this: Write a program that reads a textfile and outputs thefollowing statistics: the average line length, the longest twolines, the average word length, and the longest word. A wordis defined as a maximal sequence of consecutive characters that arenot white spaces. The static function booleanCharacter.isWhitespace(char) returns true if the input character isa white space. The program, invoked as java fileStatistics<filename>, returns the required statistics with appropriatemessages for the user. i have no idea where to even start. we are using javaprogram eclipse for this project if that matters. if someone couldplease help i would really appreciate it thank you. i'm new to programming in this language and i have no ideawhat im doing. i completed c programming but my class onlyspent 2 days on c++ so i dont know alot of those techniques used.so i have this: Write a program that reads a textfile and outputs thefollowing statistics: the average line length, the longest twolines, the average word length, and the longest word.
