A company needs to format words for display on a website. The rules for formatting are:
- If a word contains more than one occurrence of the first vowel ('a', 'e', 'i', 'o', 'u', all lowercase), replace each occurrence after the first with an asterisk (*).
Write the method formatWord that takes a String parameter word and returns the formatted string as per the rules above.
Examples:
| Input |
Output |
"eager" |
"eag*r" |
"outcome" |
"outc*me" |
"mississippi" |
"miss*ss*pp*" |
"chatbot" |
"chatbot" |

Write a class SentenceAnalyzer that analyzes a sentence (a String consisting of words separated by single spaces, with no punctuation). The class has the following methods:
public static int countWord(String sentence, String word) - to be answered in part a.public static String swapFirstLast(String sentence) - to be answered in part b.
Part a: countWord Method
Write a static method countWord that takes two parameters: a String sentence and a String word. The method returns the number of times word appears in the sentence. Two words will not match if there are case discrepancies.
Example:
countWord("java is fun and java is powerful", "java") returns 2countWord("Test test TEST", "test") returns 1
Part b: swapFirstLast Method
Write a static method swapFirstLast that takes a String sentence and returns a new String in which the first and last words have been swapped. Spaces between words must be preserved, and words are separated by a single space. If there is only one word, return the original sentence.
Examples:
swapFirstLast("coding is creative") returns "creative is coding"swapFirstLast("hello") returns "hello"
