Mehran Sahami Handout #30 CS 106A October 26, 2009 Section Handout #5: Files, Arrays, and ArrayLists Portions of this handout by Eric Roberts 1. Word count Write a program WordCount that reads a file and reports how many lines, words, and characters appear in it. Suppose, for example, that the file lear.txt contains the following passage from Shakespeare’s King Lear : Poor naked wretches, wheresoe'er you are, That bide the pelting of this pitiless storm, How shall your houseless heads and unfed sides, Your loop'd and window'd raggedness, defend you From seasons such as these? O, I have ta'en Too little care of this! Given this file, your program should be able to generate the following sample run: For the purposes of this program, a word consists of a consecutive sequence of letters and/or digits, which you can test using the static method Character.isLetterOrDigit . Also, you should not count the characters that mark the end of a line, which will have different values depending on the type of computer.
