Problem 1 [Spelling Checker] Create a hash... [FREE SOLUTION]

Chapter 9: Problem 1

[Spelling Checker] Create a hash table containing 10 spelling errors and their correct words as keys and values. For example, key appel and its value apple. Then read a string from user with spelling errors and correct them by consulting the hash table.

Short Answer

Expert verified

Define and populate a hash table with common spelling errors, read and split the user's string, correct the errors, and reconstruct the corrected string.

Step by step solution

- Define the Hash Table

First, create a hash table (dictionary) that contains common spelling errors as keys and their correct words as values.

- Populate the Hash Table

Fill the hash table with 10 key-value pairs representing the spelling errors and their corrections. For example: {'appel': 'apple', 'bananna': 'banana'}.

- Read Input String

Read a string from the user that contains spelling errors.

- Split the Input String

Split the input string into individual words to examine each word for possible corrections.

- Check and Correct Spelling Errors

For each word in the input string, check if it is a key in the hash table. If it is, replace the word with its corresponding value from the hash table.

- Reconstruct Corrected String

After correcting all possible words, join the words back into a single corrected string.

Hash Table in Java

In Java, a hash table (commonly known as `HashMap`) is a collection that stores key-value pairs. It is highly efficient for searching, inserting, and deleting operations.
A `HashMap` uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found.

To create a `HashMap`, you can use the following syntax:

HashMap corrections = new HashMap<>();

To add key-value pairs (for misspelling corrections), use the `put` method:

corrections.put(
