Word frequencies - methods

Question

Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain less than 20 words.

Ex: If the input is:

5 hey hi Mark hi mark

the output is:

hey 1

hi 2

Mark 1

hi 2

mark 1

Hint: Use two arrays, one for the strings, another for the frequencies.

Your program must define and call a method:

public static int getFrequencyOfWord(String[] wordsList, int listSize, String currWord)

Note: This is a lab from a previous chapter that now requires the use of a method.

import java.util.Scanner;

public class LabProgram {

/* Define your method here */

public static void main(String[] args) {

/* Type your code here. */

}

}

If code is not provided in the same public class it will not run.

Answer 1

....and if the user does not input the correct # of words??????

This is a problem !!! smh

Also, getFrequencyOfWord() does not accept the ARRAY of frequency counts....

and btw you do not need to pass the # of words in the list because the array.length has that;

there is better way to do this, the design is very confusing to me :-x :-(

--------------------------------------------------------------------------------------------------

import java.util.Scanner;

public class LabProgram

{

public static int getFrequencyOfWord(String[] wordsList, int listSize, String currWord)

{

int iFreqReturn = 0;

for (int iLoop=0; iLoop<listSize; iLoop++)

{

if (wordsList[iLoop].compareToIgnoreCase(currWord)==0)

{

iFreqReturn++;

}

}

return (iFreqReturn);

}

public static void main(String[] args)

{

Scanner scanner = new Scanner(System.in);

final int MAX_NUM_WORDS=20;

int N=-1;

while ((N<0) || (N>MAX_NUM_WORDS))

{

System.out.print(" Please input # of words [max=" + MAX_NUM_WORDS + "] :>");

N = scanner.nextInt();

}

String words[] = new String[N];

for (int iLoop=0; iLoop<N; iLoop++)

{

System.out.print("Please input word # " + (iLoop+1) + ":>");

words[iLoop] = scanner.next();

//System.out.println(words[iLoop]);

}

for (int iLoop=0; iLoop<N; iLoop++)

{

String curWord = words[iLoop];

int freqCount = getFrequencyOfWord(words,N,curWord);

System.out.println(" word = >" + curWord + "< : freq # = " + freqCount);

}

}

}
