Without using BufferedReader**
Students are often asked to write term papers containing a certain number of words. Counting words in a long paper is a tedious task, but the computer can help. Write a program that counts the number of words, lines, and total characters (not including whitespace) in a paper, assuming that consecutive words are separated either by spaces or end-of-line characters. Your program should be named WordCount.java. For example, the follow file:

Write a program that counts the number of words, lines, and total characters (not including whitespace) in a paper, assuming that consecutive words are separated either by spaces or end-of-line characters. Your program should be named WordCount.java. should result in the following output:
Total lines = 5
Total words = 66
Total chars = 346
Explanation / Answer
WordCount.java
import java.io.File;
import java.io.IOException;
import java.util.Scanner;
public class WordCount {
public static void main(String[] args) throws IOException {
File file = new File("words.txt");
if(file.exists()){
Scanner scan = new Scanner(file);
int wordCount = 0;
int totalChar = 0;
int lineCount = 0;
String sCurrentLine;
while (scan.hasNextLine()) {
sCurrentLine = scan.nextLine();
lineCount++;
String words[] = sCurrentLine.split("\s+");
wordCount = wordCount + words.length;
for(int i=0; i<words.length; i++){
totalChar = totalChar + words[i].length();
}
}
System.out.println("Total lines = "+lineCount);
System.out.println("Total words = "+wordCount);
System.out.println("Total chars = "+totalChar);
}
else{
System.out.println("File does not exist.");
}
}
}
Output:
Total lines = 5
Total words = 66
Total chars = 346
