- Can help in java? Define a static method, which as parameters object String (symbolizes low) and symbol and returns a Boolean value, the result of the check contained in the string. In the test function, illustrate accept the method.Write a static method called larger that accepts two double parameters and returns the larger of the two values. If the values are equal, it doesn't matter which one is returned. JAVAIn Java Write a non-static method called average that accepts two integer parameters and returns their average as a double value. Overload the average method in the above such that if three integers are provided as parameters, the method returns the double value of all three.
- Assume you are writing a unit test and want to make sure the object returned by a method is correct. We have two objects, expected (which is the object we want to get) and actual (the object the code actually returned).Which of the following is true? A. Unit tests should only check if the class variables are identical. B. We can use assertEquals(expected, actual) only if the equals method has been properly overridden, otherwise we must either check that all the getters return the same values, or that the toString returns the same value. C. We cannot compare objects directly in a unit test. D. Black box testing means we can't ever know if what is inside two objects are the same.Write a non-static method called average that accepts two integer parameters and returns their average as a double value. Overload the average method in the above such that if three integers are provided as parameters, the method returns the double value of all three.Write a program that create a class ‘simpleobject‘ , and using constructor print the following message (" MidTerm Exam ") ?

Consider as many different sorts of applications as you can—for instance: those with a GUI; those with a textual interface and a human user; those with no sort of interactive user, such as software in a vehicle’s enginemanagement system; or software in embedded systems such as a cash machine.
- in Java language : Write a program to print the area of a rectangle by creating a class named “Rectangle” with constructor having the two sides (width and height) as its parameters Test the class by creating a main class which contains the main method -->name the class “TestRectangle” Use the Scanner library to take the two sides as inputs from the console.I am trying to make a J-Unit test for a class and constructor called GameInfo class.I want to make a TestConstructor class with a method named testNameShouldNotBeNullInside testNameShouldNotBeNull, I want to write an assertThrows. In the body of the () -> { } part, call the GameInfo constructor with null for the name.GameInfo.java:Write (only) a Java static method that is your own implementation of the pow() method. The function receives two parameters – the first parameter is the value to be raised by the exponent, and the second is the exponent to raise the value to, the function returns xy. assume that the value being raised is a double and the exponent is a non-negative integer. You cannot use any built-in Java functions or methods.
