- 4. In JAVA language strings are immutable, so how can you reverse a string. Write a JAVA program to input a string and reverse the string. Display the original and reversed string in the output.In Java write a program to read Input a string and find number of lowercase alphabets in it.Write 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. The program should display: 1) The string str. 2) Your first name 3) The longest sequence matchStr. 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 = "med

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();Your task is to take 2 strings from the user and then check whether All occurrences of a character of a string must be replaced with another character of another string while preserving the order of characters of strings. Your program just print true or false. Programing language: Java
- In Java write a program to read Input a string and find number of uppercase alphabets in it.Please &-. Write a Java program to check if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward, ignoring spaces, punctuation, and capitalization. For example, "racecar" and "Madam" are palindromes, while "hello" and "Java" are not. Your program should take a string as input and return true if it's a palindrome, and false otherwise. Ik.?public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string.This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is,str = new StringBuilder(str).reverse().toString(); Here's the tester it must pass: @Test public void testPancakeScramble() throws IOException {// Explicit test casesassertEquals("", P2J3.pancakeScramble(""));assertEquals("alu",…
