Write a java class method named addQuotes that takes one parameter of type String. The method should return a string that's indentical to it's argument, but with a double quote character added at the beginning and end of the string.

basic java please    Write a method starTheString that accepts a string of any size/length and a number.  It should then return a new string that is two copies of the string with a set of stars between them equal to the number.   For example, the call of starTheString("Hello", 5) o   would return "*****Hello*****"                               5 stars - Hello - 5 Stars starTheString ("Goodbye", 3) o   would return "***Goodbye***"                           3 stars – Goodbye - 3 Stars

The makeSound() method for Pig should return: "name says: oink oink oink!" The makeSound() method for Duck should return: "name says: quack quack quack!" Where name in both cases is the value in the name attribute. create a Main.java to test your code.

modify it to create a classthat contains a static method; the method takes a string as a parameter andreturns a boolean value indicating whether the parameter string has repeatedcharacters in it or not. That is, return true if there is at least one characterwhich appear more than once in the string. The string should be input by the user   public class Qns3 {public static void main(String args[]) { //input.Scanner Input = new Scanner(System.in);System.out.println ( "Enter the String to check for duplicate characters:");String k = Input.next();// repeated = true.boolean Repeat = false;for (int i = 0; i < k.length(); i++)for (int j = i + 1; j < k.length(); j++)if (k.charAt(i) == k.charAt(j))Repeat=true;if (Repeat){System.out.println("String have repeated characters" +k);}elseSystem.out.println( "String have no repeated characters" +k);} }

Add a static method, public static void changeLetter (StringBuilder sb, char letter) Convert all occurrences of the letter variable in the StringBuilder to upper case. Write in java and use test case example as reference.

public static String[] getTokens(String raw, String delimiter){ // Line #1 goes here... int numTokens = st.countTokens(); // Line #3 goes here... for(int i = 0; i < numTokens; i++){ // Line #5 goes here } // Line #7 goes here } Using the code above, which one of these should be the code for "Line #7": ret[i] = st.nextToken(); return ret; String[] ret = new String[numTokens]; StringTokenizer st = new StringTokenizer(raw, delimiter);

3. Create a program for Smalltown Regional Airport Flights that accepts either an  integer flight number or string airport code from the options in Figure 8-33. Pass the user’s entry to one of two overloaded GetFlightInfo() methods, and then display a  returned string with all the flight details. The method version that accepts an integer looks up the airport code, name, and time of flight; the version that accepts a string description looks up the flight number, airport name, and time. The methods return an appropriate message if the flight is not found.  Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (MindTap Course List) (p. 347).

Write a java method called countA that accepts a String parameter and returns the numberof times the character 'A' is found in the string.

Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. /** * Returns a String representation of this vector. The String should be in the format "[1, 2, 3]" * * @return a String representation of this vector * @apiNote **DO NOT** use the built-in (@code Arrays.toString()} method. */…
