QUESTION
Here's A Java Calculator Program I Just Made Recently, But It Doesn't Meet My Expectations! I Want It In A More Convenient Way Like It Has 6 Classes And Some Exclamation Marks, I Wanna Get A+ So Please Help Me!
1) Can I loop the codes so after displaying the answer, It runs the code again? 2) Can I somehow decrease the number of classes and the length of codes? 3) Can I clear screen in the console like in C++, So it should display a separate view for the Intro and the answer?
Here's The Code:
...ANSWER
Answered 2018-Nov-17 at 07:52You are asking for two floats in every method and using the same prints many times, so you can just create some method such as this and call it inside your operation method to stop repeating code (constantly repeated blocks of code is a strong indicator that the block can probably be abstracted into its own method):
QUESTION
I have a simple math calculation class in JavaEE and the result is different from online java calculators. Example the website JavaCalc gives me correct result i.e. 0.0009. However, for me in my java program, the result becomes 9.xxx.
Math Equation used on above URL:
...ANSWER
Answered 2018-Jul-14 at 13:08The result is the same in calculations, but it is displayed differently. My output is
9.893141646194965E-4
which means 0.0009xxxxx. The "E" stands for scientific notation, and E-4 means move the decimal point four to the left (thus becoming 0.0009xxxxxxxxxx). It can also be written as 9.893141646194965 * 10^-4. They are the same value, but I guess that System.out.println()
converts numbers to scientific notation if that is easier to read. Java interprets these values as the same.
