in JAVA Assume that a receipt id contains characters that represent information or that can be used as a code to determine something about the purchase. For example: if an id has an 'x' followed by two 'y's, it means that the purchase was a final sale and cannot be returned. Or if an id has an 'a' followed by three 'b's, it means that a coupon was used for purchase. Write a static method for the Receipt class to test whether a receipt id meets such a criteria. Does the id meet the criteria? The criteria is described by three pieces of data, passed in as parameters: char firstTarget char second Target int countOfSecondAfter First A receipt id meets the criteria if: the id contains the first target character and the second target character appears exactly the specified number of times after the first target character appears Note: the first and second char could be the same char! Carefully review the provided driver program for examples of ids that meet and don't meet criteria. For full credit Do no import any classes from the java.util.regex package. Do not use regular expressions. (This isn't what I want you to practice in this question!) Method Header The method header in the Receipt class is: public static boolean | idMeetsCriteria (String receipt ID, char firstTarget, char second Target, int countOfSecondAfter First)

Can you help me with my java exercise

Design a class called "Person" with attributes for name, age, and gender. Implement methods to get and set these attributes, and also a method to calculate the person's age in dog years (assuming 1 dog year is equivalent to 7 human years).

JAVA. THIS IS A PROGRAMMING ASSIGNMENT NOT A WRITING ASSIGNMENT IF YOU ANSWERED BEFORE DO NOT ANSWER AGAIN PLEASE DO NOT PASTE A PAPER     Design a class to store the following information about computer scientists⦁ Name⦁ Research area(s)⦁ Major contribution A scientist may have more than one area of research.⦁ Implement the usual setters and getters methods ⦁ Implement a method that takes a research area as an input and return thenames of scientists associated with that area ⦁ Implement a method that takes a word as an input and return the names ofscientists whose contribution mention that word Next, perform desktop research to find at least five prominent black computerscientists, with their research area(s) and major contribution, and store this data intoobjects of the class you designed. You can just hardcode this data. No user input needed.Define JUnit tests to check your research area and contribution search methods.

Design a class called Stopwatch. The job of this class is to simulate a stopwatch. It should provide two methods: Start and Stop. We call the start method first, and the stop method next. Then we ask the stopwatch about the duration between start and stop. Duration should be a value in TimeSpan. Display the duration on the console. We should also be able to use a stopwatch multiple times. So we may start and stop it and then start and stop it again. Make sure the duration value each time is calculated properly. We should not be able to start a stopwatch twice in a row (because that may overwrite the initial start time). So the class should throw an InvalidOperationException if its started twice. 1
