Write a method sameVowelsStrings that takes three Strings as input. The method returns true if the three Strings contains the same unique vowels, false otherwise. Note that vowels are 'a', 'e', 'i', 'o' and 'u'

Java Method called reverse that reverses a string passed to this method as a parameter and returns the reversed string.   You should use for loop. You should not use external methods.   E.g. reverse("string") should return gnirts.     class Main {public static void main(String[] args) {}}

Write a Java method that takes a variable of type String and returns a boolean value. The method returns true if the taken string contains a valid password, false otherwise. A valid password should satisfy all the following conditions: • It can contain any character • It contains at least 6 but not more than 20 characters • The number of letters (both uppercase and lowercase) is equal to the number of digits The method's header is as follows. public static boolean password (String s) Sample run Result String s = "Hello12345"; password(s); String s = "hellohil234567"; password(s); "hi21"; password(s); true boolean b = true boolean b = String s = boolean b = false Paragraph B.

Implement a new concat method in the String class you worked on for HW2.  The method should return a new String object that represents the text you would end up with if the argument String were "added onto the end of" this String.  For example, in the code below, the String object answer should represent the text "bookstore" and true should be printed the screen. char[] bookA = {'b', 'o', 'o', 'k'}; char[] storeA = {'s', 't', 'o', 'r', 'e'}; char[] bookstoreA = {'b', 'o', 'o', 'k', 's', 't', 'o', 'r', 'e'}; String book = new String(bookA); String store = new String(storeA); String bookstore = new String(bookstoreA); String answer = book.concat(store); System.out.println(answer.equals(bookstore));     In the text area below, type in your definition of the concat method.  (In other words, type in the code that should replace the //TODO comment.)  Your code cannot call any methods.   public class String {     private char[] data;       public String(char[] value) {         data = new…

creat a method  in (java) that do the following: This will prompt the user for initial list of letters(a word).Then it will generate all permutations of these letters .Here it has to be mentioned that the permutations can also be of shorter length than the list of letters . For example, if the initial list of letters is "STOP", then "TOP" and "TOPS" are both valid permutations, but "STOPS" isn't

Write a method myConcat that takes a string of multiple words and it returns a string made up of all the words concatenated together with the whitespace removed.

The method printGroupSize() has an integer parameter. Define a second printGroupSize() method that has a string parameter. The second method outputs the following in order, all on one line: "A group of " the value of the string parameter "." End with a newline.   Ex: If the input is 7 seven, then the output is: Order for size: 7 A group of seven. 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21     public class GroupSize { publicstaticvoidprintGroupSize(intgroupSize) { System.out.println("Order for size: "+groupSize); }   /* Your code goes here */   publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intsizeOfGroup; StringsizeInWord;   sizeOfGroup=scnr.nextInt(); sizeInWord=scnr.next();   printGroupSize(sizeOfGroup); printGroupSize(sizeInWord); } }

Write a method to replace all spaces in a string with '%20'. You may assume that the stringhas sufficient space at the end to hold the additional characters, and that you are given the "true"length of the string. (Note: If implementing in Java, please use a character array so that you canperform this operation in place.)EXAMPLEInput: "Mr John Smith ", 13Output: "Mr%20John%20Smith"

Write a method called subLR take a String number and return an integer that is the subtraction of left part and right part of the numbers. If the number has odd number of digits, then we ignore the middle one. Examples: • subLR ("123456") should return -333. Because left part is 123 and right part is 456, thus 123 - 456 = -333 • subLR ("92834") should return 58. Because left part is 92 and right part is 34 (we ignore 8 because of odd number of digits), thus 92 - 34 = 58 • subLR ("-123") should return -4. Because left part is -1 and right part is 3 (we ignore 2 because of odd number of digits), thus -1 - 3 = -4 subLR ("-345020") should return -365. Because left part is -345 and right part is 020, thus -345 - 20 = -365

Define a method printStateInfo() that takes two string parameters and outputs as follows, ending with a newline. The method should not return any value. Ex: If the input is MA Massachusetts, then the output is: ++ MA ++ is Massachusetts's state code
