how do I do this one I can not figure it out

$1.$ The following program contains $6$ errors.

$```$

public class Mystery

$\{$

public static void main$($String$[]$ args$)$

$\{$

Scanner in $=$ new Scanner$("$example$.$txt$")$;

countWords$($in$)$;

$\}$

$//$ counts total lines and words in the input scanner.

public static void countWords$($Scanner input$)$

$\{$

Scanner input $=$ new Scanner$("$example$.$txt$")$;

int lineCount $=0$;

int wordCount $=0$;

while $($input$.$nextLine$())$

$\{$

String line $=$ input.line$()$; $//$ read one line

lineCount$++$;

while $($line$.$next$())//$ tokens in line

$\{$

String word $=$ line.hasNext;

wordCount$++$;

$\}$

$\}$

System.out.println$("$Lines: $"+$ lineCount$)$;

System.out.println$("$Words: $"+$ wordCount$)$;

$\}$

$\}$

$```$

Correct the errors and submit a working version of the program. The corrected version of the program should produce the following output:

Lines: $5$

Words: $21$

when it is run on the following input file, example.txt:

hello how are you

$1234$

I am fine

This line has a large number of words on it
