- public 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(); A bit convoluted, but does what is needed without fuss or muss. Maybe one day the Java strings will come with the reverse method built in, just like the string data types of all sensible…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.Homework* - Prime factors and prime numbers: Write a program that prompts the user to enter a positive integer which is greater than one and displays all its smallest factors in decreasing order. For example, if the integer is 140, the smallest factors are displayed as 7, 5, 2, 2. Use the StackOflntegers class to store the factors (e.g., 2, 2, 5, 7) and retrieve and display them in reverse order. After that, write a program that displays all the prime numbers less than the number – which is used in the prime factors (e.g: 140)- in decreasing order. Use the StackOflntegers class to store the prime numbers (e.g., 2, 3, 5, ...) and retrieve and display them in reverse order. Here is the sample runs: To use the prime factors you must enter a positive integer which is greater than one: 140 7 5 2 2 Printing prime numbers under 140: 139 137 131 127 113 109 107 103 101 97 89 83 79 73 71 67 61 59 53 47 43 41 37 31 29 23 19 17 13 11 7 5 3 2 * This homework has a part of Challenge Question.

Write a java method that receives a string containing letters of the English alphabet and then prints the Letters having unique frequencies. Notes: 1) Ignore letter case; Uppercase and lowercase letters are considered the same. 2) Do not use methods from the Arrays class.

Write a test program that prompts the user to enter a string followed by a character and displays the number of occurrences of the character in the string.Basic Java Help Each year, the Social Security Administration provides a list of baby names for boy and girls by state. You will write a program to read a file containing a list of baby names and display the top names. To start, implement the following class: baby names util = printTopNames(File, int): void printTopNames Will be a static method. It will accept two parameters, one is a File containing the list of names. The other is an integer that indicates how many names to display (ie, top 10 names, or top 50 names, etc). The integer argument could be any valid integer. You do not have to worry about an integer value large than 5 for the boy/girl names. This method should open the file and parse the file and print the names as shown below: Your program will use the Scanner class to read the data from the file (see your text for examples). You will also need to use a delimiter with the scanner so that the scanner will break the line apart based on the commas. For this file, set…Find the body for: def contains_no_lowercase_vowels(phrase: str) -> bool: """Return True iff (if and only if) phrase does not contain any lowercase vowels. >>> contains_no_lowercase_vowels('syzygy') True >>> contains_no_lowercase_vowels('e') False >>> contains_no_lowercase_vowels('abc') False """
