- In Java, Use the Phone class as a baseline, and write a method isUSA. It should return true if the country code is 1 and false otherwise. Also expanding the Phone class, write a method that determines the location of an area code. It should return the name of the area code's city. For example, if cc = 1 and area code = 510 East Bay Area, 650 SF Peninsula, 415 San Francisco, 408 South Bay Area. For this assignment, use literal strings as return values.In java: Complete the checkCharacter() method which has 2 parameters: A String, and a specified index (int). The method checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character. Ex: The method calls below with the given arguments will return the following Strings: checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"You can just provide code as you don't have required utility class, Please provide explanation and comments for code : Write a static method asciiGraph(), to display a “graph” of ASCII values of a String. 2.The method has a single String parameter str, and returns nothing (void).3.The method loops through all characters in str, and for each displays a line of *s on a row equal to the ASCII/Unicode integer value of the character being examined (see example).Hints:1. recall the String methods .charAt() and .length(), and casting a char with (int) directly returns the int ASCII/Unicode value2. to produce the line of *s, call the method starLine() from the Exam utility class3. in the output capture document, consider reducing the font size to 7 or 8 point to have each row of *s on a single line Consider the strings “Ab C” and “TED 99”, that are composed of:A displays 65 stars (*), since Unicode 65 = 'A'b 98 stars (*), since Unicode 98 = 'b'space 32 * , since Unicode 32 = ' ' (the space)C…

In the main method, ask user to enter a string for your method’s parameter and print the output of your method. Output: Enter a string abcde edcba1. Write a Java program that will ask for a string of letters . 2. Each letter in the alphabet is given the following number code as assignment . 3. Print out the number code of each letter from the input in reverse . 4. Ask if the operation should be done again, if Yes, Return to 1. if No. Terminate the program 5. Create at least 2 methods aside from your main method in implementing a solution for this problem.
- 6. Write a method that reads three strings from the keyboard. Although the strings are in no particular order, display the string that would be second if they were arranged lexicographically. 7. Write a method that reads a one-line sentence as input and then displays the following response: If the sentence ends with a question mark (?) and the input contains an even number of characters, display the word Yes. If the sentence ends with a question mark and the input contains an odd number of characters, display the word No. If the sentence ends with an exclamation point (!), display the word Wow. In all other cases, display the words You always say followed by the input string enclosed in quotes. Your output should all be on one line. Be sure to note that in the last case, your output must include quotation marks around the echoed input string. In all other cases, there are no quotes in the output. Your program does not have to check the input to see that the user has entered a…Use Java program to add a method printReceipt to the CashRegister class. The method should ask the user to input the 5 items that they have bought recently and also the prices for each item. Next, print the items, their prices, and the total amount due. Hint: You will need to form a string of all prices. Use the concat method of the String class to add additional items to that string. To turn a price into a string, use the call String.valueOf(price). Also, the payment information will need to be the same as the price information. Here is the CashRegister class: /** A cash register totals up sales and computes change due.*/public class CashRegister{ private double purchase; private double payment; /** Constructs a cash register with no money in it. */ public CashRegister() { purchase = 0; payment = 0; } /** Records the sale of an item. @param amount the price of the item */ public void recordPurchase(double amount) { purchase =…Write a Java method named check() that checks the validity of a password received as string parameter. To be valid, a password should contain at least: 3 letters, 2 digits, and 1 character from {‘-’, ‘_’}. If the password is valid the method returns true, otherwise it returns false. To test your method, write a main() method that enables the user to input a password as a string, removes eventual extra spaces from it, sends it to check(), and displays the returned decision (the password is valid or not).
