Given the String String str = “Zhrx.aghkio.Gko123”; (a) Write Java code using the String class methods indexOf and substring to extract the three string surrounded by the periods. In other words String s1 will contain Zhrx, String s2 will contain aghkio and String s3 will contain Gko123. (b) Write a method of the form public static String minstr(String str1, String str2) which returns the string which is “smaller” based on the decimal values of the characters in the string. Thus, Zaa would be “smaller” than bxy because the character Z has a lower decimal values than b. Use the String method compareTo as part of your code. (c) In main, print the value returned by minStr(minStr(s1,s2),s3)
Using the objects you just created, as shown below, call the method to change the access level to the next in the sequence (in C++). CODE: #include <iostream>using namespace std; class ParkingLot {private: bool Paid; bool Up; bool Down; public: ParkingLot() { Paid = false; Up = false; Down = true; } ParkingLot(bool paid, bool up) { Paid = paid; Up = up; Down = !up; } void togglePaid() { Paid = !Paid; if (Paid) { Up = true; Down = false; } else { Up = false; Down = true; } } bool isPaid() { return Paid; } bool isUp() { return Up; } bool isDown() { return Down; }}; int main() { // create a ParkingLot object using the default constructor ParkingLot lot1; // create a ParkingLot object using the overloaded constructor ParkingLot lot2(true, false); // display initial state of the…
In Java please 6.20 LAB: Hailstone sequence (EO) Given a positive integer num, the following rules will always create a sequence that ends with 1, called the hailstone sequence: If num is even, divide it by 2 If num is odd, multiply it by 3 and add 1 (i.e. 3*num +1) Continue until num is 1 Write a method, hailstone(), that takes in a positive integer as a parameter and prints the hailstone sequence starting with that integer. Format the output so that ten integers, each separated by a tab character (\t), are printed per line. Assume the input to the program is always positive. The output format can be achieved as follows:System.out.print(num + "\t"); Ex: If the program input is: 25 the output of method hailstone() is: 25 76 38 19 58 29 88 44 22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1 Note: Your program must define the method:public int hailstone(int num) import java.util.Scanner; public class Hailstone { public static void hailstone(int num){int i =…
In Csharp (C#) a) Create a method that creates six random numbers between 10-20 which the method shall then return the numbers generated through reference parameters. b) Create a method that has six parameters and can accept in six numbers, where the function must return true if all numbers are equal to each other from a) c) Create a Method with a timer, it should have a delay of about 150ms. For each Tick event the numbers will randomize themselves as in task a). Have a variable count up the amount of ticks. The Method should be able to be stopped on demand as well through a button click.
Define stubs for the methods called by the below main(). Each stub should print "FIXME: Finish methodName()" followed by a newline, and should return -1. Example output: FIXME: Finish getUserNum() FIXME: Finish getUserNum() FIXME: Finish computeAvg() Avg: -1 import java.util.Scanner; public class MthdStubsStatistics { /* Your solution goes here */ public static void main(String [] args) {int userNum1;int userNum2;int avgResult; userNum1 = getUserNum();userNum2 = getUserNum(); avgResult = computeAvg(userNum1, userNum2); System.out.println("Avg: " + avgResult);}}
java Create a method called next3() that will take an int argument and print the three numbers that come after the given number. The next3() method is already called in the main method. Print in the following format: $number1 $number2 $number3 The three next numbers are printed on the same line with spaces between them This is a void method with an int parameter
Java Programming: Below is the shank.java file which is the main method file along with shank.txt.

In this task, you are asked to write a program called Swap.java, including at least 3 following methods: Main() swapDigitPairs ( parameter) swapLetterPairs (parameter) In the main method, Use your Panther Number as the input argument, call swapDigitPairs ( parameter) Ask user to input a number and call a method swapDigitPairs to swap the number as shown in the example of the following figure. Ask the user to input a string of letters/numbers and call a method swapLetterPairs to swap the letters as shown in the following example. The method swapDigitPairs accepts an integer n as a parameter and returns a new integer whose value is similar to n’s but with each pair of digits swapped in order. For example, the call of swapDigitPairs(482596) would return 845269. Notice that the 9 and 6 are swapped, as are the 2 and 5, and the 4 and 8. If the number contains an odd number of digits, leave the leftmost digit in its original place. The method swapDigitPairs should not use String class…
