1. A showChar MethodWrite a method named showChar. The method should accept two arguments: a reference toa String object and an integer. The integer argument is a character position within theString, with the first character being at position 0. When the method executes, it shoulddisplay the character at that character position. The method does not return anything.Here is an example of a call to the method:showChar("New York", 2);In this call, the method will display the character w because it is in position 2. Demonstratethe method in a complete program-- use the class name Method_showChar
Java
Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
Word Counter Create an application with a method that accepts a string as an argument and returns the number of words it contains. For instance, if the argument is "Four score and seven years ago," the method should return the number 6. The application should let the user enter a string, and then it should pass the string to the method. The number of words in the string should be displayed.

- Pattern and Value are two strings that you must use. The pattern string, which denotes a pattern inside a string, is made up just of the letters a and b. For instance, the string catcatgocatgo matches the pattern aabab (where cat is represented by letter A and go by letter B). Additionally, it matches a, ab, and b pattern. To check whether a value matches a pattern, create a method.arrow_forwardVowels and Consonants Create an application with a method that accepts a string as an argument and returns the number of vowels that the string contains. The application should have another method that accepts a string as an argument and returns the number of consonants that the string contains. The application should let the user enter a string, and should display the number of vowels and the number of consonants it contains.arrow_forwardC sharp Write a method that accepts a string as an argument and checks it for proper capitalization and punctuation. The method should determine if the string begins with an uppercase letter and ends with a punctuation mark. The method should return true if the string meets the criteria; otherwise, it should return false.arrow_forward

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 stringarrow_forwardPig Latin is a nonsense language. To create a word in pig Latin, you remove the first letter and then add the first letter and ay at the end of the word. For example, dog becomes ogday and cat becomes atcay.
