Chapter 16. PC #3. String Reverser (page 1073)
Write a recursive method that accepts a string as its argument and returns the string in reverse order. The method should return the same string if the string length is less than 2 characters long. The main program should ask the user to enter a string, which is then reversed using the above method and printed on the console. The program then prompts the user to enter another string. If the user enters QUIT (case insensitive), then exit the program.
Test Case 1

- Question 4. Recursion write a Java program.A perfect number is a number whose factors, excluding the number itself, also add up to that number.For example 6 is a perfect number since its factors (other than 6 itself) 1, 2, and 3 also add up to 6 (i.e.,1+2+3 = 6).

It will have two static methods: removeX and countSubstring and write each function recursively. Recursion class removeX The removeX function will take a String as a parameter. It will return a new String that is the same as the original String, but with all “x” characters removed. This method will be case insensitive. countSubstring The countSubstring function will take two strings as parameters and will return an integer that is the count of how many times the substring (the second parameter) appears in the first string without overlapping with itself. This method will be case insensitive. For example: countSubstring(“catwoman loves cats”, “cat”) would return 2 countSubstring(“aaa nice”, “aa”) would return 1 because “aa” only appears once without overlapping itself. Create a Main class to test and run your Recursion class.arrow_forward
- Complete the following program Countdown.java. This program uses recursion to count down from a user input number. The output should be exactly like what is in the picture below. The code should be completed in the spots where it states "complete here"arrow_forwardDemonstrate Recursion Assignment Instructions Overview The programs we’ve discussed so far are generally structured as methods that call one another in a hierarchical manner. For some problems, it’s useful to have a method call itself—this is known as a recursive method. Such a method can call itself either directly or indirectly through another method. Recursion is an important topic discussed at length in upper-level computer-science courses. Instructions Write a recursive method printArray() that displays all the elements in an array of integers, separated by spaces. The array must be 100 elements in size and filled using a for loop and a random number generator. The pseudo-code for this is as follows: //Instantiate an integer array of size 100 //fill the array For (int i=0; i<array.length; i++) Array[i] = random number between 1 and 100 inclusive printArray(integer array); For this assignment make sure that your screen shots show your program running and that your runtime…arrow_forwardT/F: All recursive algorithms are efficient due to its recursive property.arrow_forward
- Class Utilities { Method Details addDelimiter: public static java.lang.String addDelimiter(java.lang.String str, char delimeter) Returns a string where characters are separated by the specified delimeter character. A string with a single character will not have a delimeter added. The space character is consider a character (similar to character 'A'). You can assume str will never be the empty string. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. Note: In java given two characters a and b, a + b will not create a string. To create a string, append a to the empty string and the result to b. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: str - delimeter - Returns: String with characters…arrow_forwardComplete the following program Multiply.java.

You can assume str will never be null. You can use Character.isDigit() to determine whether a character is a digit. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring.
