Question

Write a method called inputStats that accepts a Scanner representing an input file and reports the number of lines, the longest line, the number of tokens on each line, and the length of the longest token on each line. If the file contains the following text:

Beware the Jabberwock, my son, the jaws that bite, the claws that catch, Beware the JubJub bird and shun the frumious bandersnatch.

For the input above, your method should produce the following output:

Line 1 has 5 tokens (longest = 11) Line 2 has 8 tokens (longest = 6) Line 3 has 6 tokens (longest = 6) Line 4 has 3 tokens (longest = 13) Longest line: the jaws that bite, the claws that catch,

Answer 1

CODE

import java.util.Scanner;

public class Main {

public void inputStats(Scanner sc) {

int numLines = 0;

int maxLineLength = 0;

String longestLine = "";

while(sc.hasNextLine()) {

numLines ++;

String line = sc.nextLine();

if (line.length() > maxLineLength) {

maxLineLength = line.length();

longestLine = line;

}

String[] tokens = line.split(" ");

int maxTokenLength = 0;

for (String token : tokens) {

if (token.length() > maxTokenLength) {

maxTokenLength = token.length();

}

}

System.out.format("Line %d has % tokens (longest = %d)\n", numLines, tokens.length, maxLineLength);

}

System.out.println("Longest Line: " + longestLine);

}

}
