Removing all the punctuations from a string

Program plan:

Create a class StringBuilder to remove all the punctuation stored in a string.

In main() function,

Initially, assign the original string in variable.

Then, invoke the removeIt()function to remove all the punctuation in a string and store the final value in original string.

Display the string after removing the punctuation in console screen.

In the method removeAt(),

It passes input parameter “s” to check whether the character contains punctuation in the string. If yes, then it removes all the punctuation stored in the string “s”.

For loop read all the characters from a sentence until the condition leads to false.

Then, it calls the function ok() and check whether the character at “j” position matches with the character or not.

If the result returns the Boolean value false, then delete the character at the specified position in “j” otherwise store the character using Tostring() method in “s” variable.

In the method ok(),

It passes input parameter “i” to check whether the character in the sentence matches with the corresponding ASCII values.

If yes, then it returns the Boolean value true otherwise it return false.
