JAVA BEGINNER PROGRAM
Write a scientific calculator applying functions in java.lang.Math class and provide the following capabilities:
1. Perform arithmetic operations (+, -, /, *, ^ and %) on any two values. Your program should be able handle negative values using integers only.
2. Perform the following scientific operations (sin, cos, tan, floor, ceiling, square root, cuberoot, log, log10 and round) using doubles.
3. Print min and max of two values using a double.
You must write a separate static function for each operation. Display all operations available in your calculator. Once user selects the operation, the program should guide the user for input and provide the results. User should not have to restart the program for every new operation but the program should run unit user chooses to quit.
You need to show output testing every function.
