Given a String str, find and print the shortest words. The String will have multiple words separated by commas and spaces. If there is words that have the same length, they should all be displayed at the end. Print all the shortest words in the following format:
Input: word1, word2, word3, word4, etc...
Output: [short1, short2, short3, etc...]
Hint: Think about what comes between each word in the sentence
Main topics: arrays, String, loops, if statements, primitive datatypes, operators
Example:
Input:
olive, fish, pursuit, old, warning, python, java, coffee, cat, ray
Output:
[old, cat, ray]
Scanner scan = new Scanner(System.in); String str = scan.nextLine();

Each character that occurs more than 2 times in a row is represented by the character and a number following it.

The string can contain all the alphanumeric and other special characters as well. However, only the lowercase English alphabets are allowed in the String.arrow_forwardLanguage: Java Write a program that reads a sentence from the keyboard. Depending on the last character of the sentence, print the message identifying the sentence as declarative (ends with a period), interrogative (ends with a question mark), exclamatory (end with an exclamation point), or other. Hint: you can use charAt() method from the String class to extract the last character of the input line. The character of a String str is at str.length()-1 position. For taking a sentence as input use the nextLine() method from the Scanner class. You have to use if/else if selection. Sample input and output: Sample 1 Input: How are you? Output: Interrogative Sample 2 Input: I am good. Output: Declarative Sample 3 Input: That is amazing! Output: Exclamatory Sample 4 Input: Although, Output: Other Answer:arrow_forward

Note: In Random String str we can have at most two subsequent similar letters (we can have Aa but not AaA or aaa) Example: Suppose the generated random String is "AmedMoXMha" Name is "Mohamed" Output: Str = "Amed MOXMha" Name = "Mohamed" MatchStr = "medarrow_forwardWrite a java program that generates random string called str of 10 characters from the English alphabet (lower and upper case) and then find the longest sequence of characters from str that is also a substring in your First Name called matchStr.

Today he found an old rope in his garage. The string is so old that some of its characters have disappeared and cannot be identified now. Blurred letters in the character unit are represented by '.' and the other letters are Latin letters of the word ['a' - 'z']. The palindrome tom has decided to build a very small palindrome according to the dictionary by filling in each diminished letter ('.') In Latin with a lowercase letter.
