Java Programming – Lesson 4 Using Methods – Laboratory ExercisesCreate a class whose main() holds two integer variables. Assign values to the variables. Create two methods named sum() and difference, that compute the sum and difference between the two variables respectively. Each method should perform the computation and display the results. In turn, call the two methods passing the values of the 2 variables. Create another method named product. The method should compute the product of the 2 numbers but will not display the answer. Instead, the method should return the answer to the calling main() which displays the answer. Provide your own screen display and class name.Create a class whose main() holds an array containing 10 integers. Create two methods that accepts the array. The first method named lowest returns the lowest from the 10 numbers while the second method named highest returns the highest number from the list. Determine the highest and lowest number without sorting the numbers. Your output should contain the original list of numbers, the highest and the lowest number from the list. Supply the necessary values for the arrayCreate a class named Commission that includes 3 variables: a double sales figure, a double commission rate and an integer commission rate. Create 2 overloaded methods named computeCommission(). The first method takes 2 double arguments representing sales and rate, multiplies them and then displays the results. The second method takes 2 arguments: a double sales figure and an integer commission rate. This method must divide the commission rate by 100.0 before multiplying by the sales figure and displaying the commission. Supply appropriate values for the variables. Test each overloaded methods.
