Concept explainers
Modify your printDetai 1 s method to include printing the reference number. However, the method should print the reference number only if it has been set-that is, if the refNumber string has a non-zero length. If it has not been set, then print the string "ZZZ" instead. Hint: Use a conditional statement whose test calls the 1ength method on the refNumber string.

- should provide a method to set a large value as string (e.g. .: "862758250540736047343432411236541 ")arrow_forwardProblem: To write the JUnit test cases for our methods, you need to create two test methods: testLeapYear: This method should test if the isLeapYear method returns true for a given leap year. For example, you can choose the year 2020 and verify if the method returns true for it. If it does, the test will pass. If it doesn't, the test will fail. testNotLeapYear: This method should test if the isLeapYear method returns false for a given non-leap year. For example, you can choose the year 1900 and verify if the method returns false for it. If it does, the test will pass. If it doesn't, the test will fail. --------------------------------------------------------------------------------------------------------------------------------------------------------- import static org.junit.jupiter.api.Assertions.assertTrue; import org.junit.jupiter.api.Test; public class LeapYearTest { // Test case to check if a year is a leap year @Test public void testLeapYear() { //create…arrow_forwardFix the error(s) in the following line of code.decRoyalTitle = strRoyalTitle(Text.StringLength)arrow_forward
- Imagine that the String toUpperCase method did not exist and you were asked to write one. You can't use the String toUpperCase method, but you can use methods on Character. Hint: There is a method Character.toUpperCase(char) which converts a char to uppercase. Hint: There is a method Character.toString(char) which converts a char to a String.arrow_forwardPlease help me this I need answer typing clear urjent no chatgpt used i will give 5 upvotesarrow_forwardThis method simulates the playing of one round of “Rock Paper Scissors”. In this strange version of the game, if both players have the same hand gestures, the return value is 1. If they have different hand gestures, the return value is a 0. If at least one player, provides a string argument that is anything other than rock, paper, or scissors, the return value is -1. The method should not be case-sensitive. For example, rock, ROCK, Rock, and RocK are all valid. Can’t use system.out.println. You return it. The output should be -1 0 1 In c++arrow_forward

- You are responsible for adding the appropriate testing code to your main. a. The getValedictorian method returns the valedictorian of the class, that is the student with the highest grade point average. Implement this new method. b. The getHonorsPercent method returns the percentage of students in the class who are in the honors program. Use 3.75 as the cutoff GPA. Implement this method. Also print the list of students, by using the isHonor method, in the Honors program. c. An alternate implementation for the School class is being considered, in which the students are stored in an ArrayList instead of an array. Show how the declaration of the data field students would look in this alternate design. MAIN CLASS: import java.util.ArrayList; public class Main { public static void main(String[] args) { System.out.println("Unit07Project2 by Your Name"); System.out.println(); int size = 10; School onw = new School(size); /* Add the code…arrow_forwardnote: You can easily replace a portion of text within a String using the String method "replace()". For example: String svar = "raspberry jam"; svar = svar.replace("jam", "pie"); System.out.println(svar); will print out: raspberry pie A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output.arrow_forwardWrite a method that counts the number of letters ina string using the following header:public static int countLetters(String s)Write a test program that prompts the user to enter a string and displays the numberof letters in the string.arrow_forward
