Explanation of Solution
Given statement:
//Store the name in the StringBuilder object
StringBuilder name = "Joe Schmoe";
Error in the given statement:
“StringBuilder” class:
- The class “StringBuilder” is similar to the class “String” except the way the changes are made to the objects of the “StringBuilder”.
- The contents of the “StringBuilder” object can be changed whereas the contents of the “String” object cannot be changed...

Look at the following statement: String city = "Asheville";Rewrite this statement so that city references a StringBuilder object instead of a String object.
If you write this method for a class, Java will automatically call it any time you concatenate an object of the class with a string.a. toStringb. plusStringc. stringConvertd. concatString
JAVAA7-Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of vowels in the string, and another method that returns the number of consonants in the string. Demonstrate the class in a program by invoking the methods that return the number of vowels and consonants. Print the counts returned.

CarDealership Class The CarDealership class will simulate a real life automotive dealership. This class will create 3 Car objects and store them in an array named Lot. The class will then display all of the information pertaining to each car (color, make, model, etc.) to the User and allow the User to select one to purchase. Once the User selects a car to purchase, the Car object should be removed from the array (Lot) and another Car object should be put in its place.arrow_forwardpublic 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",…arrow_forwardIn the class String, the substring method inserts a String into another String. -True or -Falsearrow_forward
- 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_forwardAlternate 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”.

This class also contains another String field called: ”mixedResult” which is only defined globally and will be initialized using a method in the future in the main class namely the mix method. The public String toToken() method is a method that will use the initialValue field and it for the letter ’p’ or the letter ’A’. If it finds the letter, every element on the left side of the found letter will be stored in another string and returned. Example: If the initialValue was: ”This is a possible resource allocation”. The returning String will be: ”possible resource allocation”. Use control statements here iterate through the string using a counter control…arrow_forward
