In your definition for the Withdraw method, check if the account has sufficient funds before making a withdrawal. Apply transaction fees as per the table above:True or False: If methodA() has an equals() method that overrides the one in the Object class, then in our JUnit test for methodA(), assertEquals() will use the version of equals() in methodA().Java Code Please Output For each of the getter methods that gets called, the values they return must be printed.

- Allow the user to automatically flip a coin 500 times. Keep track of the number of times heads and tails appear. Also, keep track of "heads" winning streaks and "tails" losing streaks. That is, keep track of how many times 1 head in a row occurs, 2 heads in a row, 3 heads in a row and so on, and the same for tails. Be sure to separate all functions and methods (if you chose to use a class or structure) into both the prototype and an implementation below the main. 1. Write a regular c-type function that returns a random bool 1 = "heads" and 0 = "tails". Use the following prototype: bool coinFlip(void); 2. When the user plays the game, flip the coin 500 times automatically. Keep track of the number of "tails that come up", "heads that come up", the number of "heads" winning streaks as well as the "tails" losing streaks. The output may look something like this, where the code was only run 100 times: You flipped a coin 100 times:Number of heads = 54Number of tails = 46Heads winning…What will be returned from the following method? public double testing ( ) { double a = 9.5 + 9.3; return a; }If you don't decalre a method as public or private, would the method be defaulted to public, private or something else?

- Problem: 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…Overriding a method differers from overloading a method because: a) Overloaded methods have the same signature b) Overridden methods have the same signature c) Both d) NeitherWhat will be returned from the following method? public double testing ( ) { double a = 9.5 + 9.3; return a; } a) 18.8 b) 18.0 c) 18 d) 19
- Now for a creative Java program. Write an original class with at least two methods that demonstrate method overloading. Execute all of the overloaded methods in the main method. In comments clearly show that you understand overloading and how your methods illustrate overloading.2. which debugging method should be used when all other methods fail? A. Backtracking B. Deduction C. Brute force D. InductionTrue or FalseIt is a common practice to make all a class’s fields private and to provide access to those fields through methods.
