In Java Please

Part $1$: $($Implemented for you$)$

Pass in the name of the file as input.

For example we$$ll have input File$1.$txt

From there read the content of the File one word at a time using a while loop.

Create a tally called countInt, countFloat, countWord, and countSymbol.

Part $2$:

Implement Method $1$:

Public static boolean isTokenInt$($String token$)\{$

$\}$

This method takes a String and determines if its content is an integer

Here is how an integer is defined

$($Optional $[+$ or $-]$ followed by one or more digits $[0|1|2|3|4|5|6|7|8|9])$

In grammar form

integer $->[$sign$]$ digit

sign $->+|-$

digit $->$ number $|$ number $[$digit$]$

number $->0|1|2|3|4|5|6|7|8|9$

$$

Go through the String token one character at a time and see if it meets the requirement above

Return true if it$$s an integer

Return false otherwise

Implement Method $2$:

Public static $$boolean isTokenFloat$($String token$)\{$

$\}$

This method takes a String and determines if its content is a float

Here is how a float is defined

$($Optional $[+$ or $-]$ followed by zero or more digits $[0|1|2|3|4|5|6|7|8|9]$

Followed by $[.]$ followed by one or more digits $[0|1|2|3|4|5|6|7|8|9])$

In grammar form

float $->[$sign$][$digit$].$digit

sign $->+|-$

digit $->$ number $|$ number $[$digit$]$

number $->0|1|2|3|4|5|6|7|8|9$

Go through the String token one character at a time to see if it meets the requirements above.

Return true if it$$s a float

Return false otherwise

$$

Implement Method $3$:

Public static boolean isTokenWord$($String token$)\{$

$\}$

This method takes a String and determines if its content is a word

Here is how a word is defined

$($one or more letters $[[$A$-$Z$]|[$a$-$z$]])$

Go through the string token one character at a time to see if it meets the requirements above.

Return true if it$$s a string

Return false otherwise

Part $3$:

If method $1$ returns true increase countInt by $1.$ If method $2$ returns true increase countFloat by $1,$ if method $3$ returns true increase countWord by $1,$ otherwise increase countSymbol by $1$

$$

Part $4$: $($Implemented for you$)$

At the end of the while loop print out the following

$$

The file is $($filename$)$

$($Filename$)$ contains $($countInteger$)$ integers

$($Filename$)$ contains $($countFloat$)$ floats

$($Filename$)$ contains $($countWord$)$ words

$($Filename$)$ contains $($countSymbol$)$ symbols

$$

Part $5$: $($OPTIONAL FOR $4$ EXTRA POINTS$)$

Enhance Method $3$:

Public static boolean isTokenWord$($String token$)\{$

$\}$

This method takes a String token and determines if its content is a word

Use the following to determine if it$$s a word accounting for grammar symbols

$($one or more letters $[[$A$-$Z$]|[$a$-$z$]])$ followed by optional $(,|$ : $|!|.|?|$ ;$))$

Go through the string token one character at a time to see if it meets the requirements above.

Return true if it$$s a string

Return false otherwise
