Now, find the length of the obtained array. Learn how to electronically sign a Word document online using jSign.Now, split the above string into an array of strings using the split() method by passing the regular expression of the new line as a parameter to this method.Instantiate a String class by passing the byte array obtained, as a parameter its constructor.Read the contents of the file to a bytearray using the read() method of FileInputStream class.

The words extracted are copied into and returned as an array whose length is the number of words in your file. Instantiate the FileInputStream class by passing an object of the required file as parameter to its constructor. So wherever there is a space, line break or hyphen, the sentence will be split. Read file line-by-line using while-loop and increase lineCount variable by 1 (starting from 0, already initialised at the top of method) For every line, split String using space as delimiter & assign it to temporary. At the end of the article, we also show the performance of the different ways of counting the total number of lines in a large file that contains 5 million lines and 1053 characters per line. Instantiate the FileInputStream class by passing an object of the required file as parameter to its constructor. int numwords line.split('\\s\\-').length //stores number of words ('Number of words in file is '+numwords) REGEX (Regular Expression): \\s splits the String at white spaces/line breaks and \\-at hyphens. Steps for counting words and lines: First write logic to read file from local drive location using BufferedReader & FileReader. Read line by line, and increases count + 1 each line.
