Question

Create an application named ArithmeticMethods whose main() method holds two integer variables. Assign values to the variables. In turn, pass each value to methods named displayNumberPlus10(), displayNumberPlus100(), and displayNumberPlus1000(). Create each method to perform the task its name implies. Save the application as ArithmeticMethods.java. Submit code below.

Paste your Code Answer here:

Modify the ArithmeticMethods class to accept the values of the two integers from a user at the keyboard. Save the file as ArithmeticMethods2.java. Submit code below.

Create an application named Percentages whose main() method holds two double variables. Assign values to the variables. Pass both the variables to a method named computePercent() that displays the two values and the value of the first number as a percentage of the second one. For example, if the numbers are 2.0 and 5.0, the method should display a statement similar to “2.0 is 40% of 5.0.” Then call the method a second time, passing the values in reverse order. Save the application as Percentages.java. Submit code below.
