- private float c; private void method2(double y) { c = y; } in another class we created an object of the first class then within in it : tester.method2 (10.0f); are there any errors ? how many errors if there are any and with explanation please.//Todo write test cases for SimpleCalculator Class // No need to implement the actual Calculator class just write Test cases as per TDD. // you need to just write test cases no mocking // test should cover all methods from calculator and all scenarios, so a minimum of 5 test // 1 for add, 1 for subtract, 1 for multiply, 2 for divide (1 for normal division, 1 for division by 0) // make sure all these test cases fail public class CalculatorTest { //Declare variable here private Calculator calculator; //Add before each here //write test cases here }private int b; public int method3() { return b; } // in another class an object of the first class was introduced and inside the second class : float y = tester.method3(); are there any errors ? and explain please
- public class utils { * Modify the method below. The method below, myMethod, will be called from a testing function in VPL. * write one line of Java code inside the method that adds one string * to another. It will look something like this: * Assume that 1. String theInput is 2. string mystring is ceorge неllo, пу nane is * we want to update mystring so that it is неllo, пу nane is Ceorge */ public static string mymethod(string theInput){ System.out.println("This method combines two strings."); Systen.out.println("we combined two strings to make mystring); return mystring;ANSWER IN JAVA Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Add a main method to the class that demonstrates class Date's capabilities.Problem No. 2 Write a Java class called ContainsInRange. This class defines a method called contains(), which takes as parameters an integer array a, an integer x, an int called start, as well as an int called end, and returns a boolean which is true if and only if x occurs in a at a position which is greater than or equal to start, and less than end. You must validate that start is less than or equal to end, and that both start and end are greater than or equal to 0, and less than or equal to a.length. Repeat the operation often. (please put also the code that the user can enter a value. Thank you)
- Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.write code in java write a static method that will take in a lone integer parameter. this function will return 1 if the number provided is odd, 0 if it is even. write a line of code that will call the function you just wrote above, passing it the contents of a variable called value and have it assigned the value returned by the function another variable called answer(both variables are already declared.)i. Design a class for with method accepting the following input: - Minimum range ex. minr = 1500 - Maximum range ex. maxr = 2701 - Divisibility with this first number ex. div1 = 5 - Divisibility with this second number ex. div2 = 7 ii. Output will be list of numbers that are divisible by div1 and div2, between minr and maxr iii. Use while loop
- 30. True or False: The parameterized constructors of Java does not accept any parameters instead, using these constructors the instance variables of a method will be initialized with fixed values for all objects. False True Give an explanation for the answer. Thank youpublic float method1(int z) { return (float) z; } // in another class we created an object of the first class and within in it: int y = tester.method1(); are there any errors ? with explanation please1.
