Write a method called wordCount that accepts a String as its parameter and returns the number of words in the String. A word is a sequence of one or more nonspace characters (any character other than ' '). For example, the call wordCount("hello") should return 1, the call wordCount ("how are you?") should return 3, the call wordCount(" this string has wide spaces ") should return 5, and the call wordCount(" ") should return 0.

Methods of StringBuilder class

The StringBuilder class can be used to create mutable strings. The methods defined in the StringBuilder class are widely used to manipulate and concatenate strings. It is a non-synchronized class which has public methods that can be accessed by multiple threads. It is not thread-safe.

hello im stuck on a problem and it would be great if you could create a program that prompts the user for a message to encode,as well as an offset to encrypt it with. You will then create and use the following methods:• A validation method that takes in the message (as a string) and the offset integerentered by the user. The method should return “true” if the offset is between 0and 26 inclusively and the message contains only letters and spaces. If it failseither criteria, it should return “false”.• If the validation method returns true, a second encryption method should becalled. This method also takes in the message (as a string) and the offset integerentered by the user. It should convert the message to UPPERCASE, encryptevery letter in the message, and leave the spaces as they were. It should thenreturn the encrypted message. i attached an image of the sample output

In some cases, a class depends on itself. That is, an object of one class interactswith another object of the same class. To accomplish this, a method of the classmay accept as a parameter an object of the same class.The concat method of the String class is an example of this situation. Themethod is executed through one String object and is passed another String object as a parameter. Here is an example:str3 = str1.concat(str2);The String object executing the method (str1) appends its characters to thoseof the String passed as a parameter (str2). A new String object is returned asa result and stored as str3. Write java code to implement given conditions

This is the question and needs to be written in java: Write an application that accepts three unique Strings from the user and, without regard to case, appropriately displays either You did not enter the words in alphabetical order or You entered the strings in alphabetical order depending on whether the Strings were entered in alphabetical order.
Create an application that reads a sequence of up to 25 names and postal (ZIP) codes for persons. Put the data in an object that can have a first name (string), last name (string), and postal code (integer). Assume that each line of input will have two strings separated by a tab character, followed by an integer value. After the input has been read in, print the list to the screen in the appropriate manner.
Ex: Use getline() to get a line of user input into a string. Output the line. Enter text: IDK if I'll go. It's my BFF's birthday. You entered: IDK if I'll go. It's my BFF's birthday. Search the string (using find()) for common abbreviations and print a list of each found abbreviation along with its decoded meaning. Ex: Enter text: IDK if I'll go. It's my BFF's birthday. You entered: IDK if I'll go. It's my BFF's birthday. BFF: best friend forever IDK: I don't know Support these abbreviations: BFF -- best friend forever IDK -- I don't know .
