Modulus of 3's
/* Instructions:
* Return true if the given non-negative number is
* a multiple of 3 or a multiple of 5.
*
* Use the % "mod" operator
*
* or35(3) → true
* or35(10) → true
* or35(8) → false
*
* Note: your value for this exercise will be different based on your seat number

PX_JavaOperators_lastname(4 files)
Purpose: To build a java programs that shows all the java operators..
/* Instructions:
* Copy the java program code below.
*/
You will need to create the following 4 files:
PX_JavaOperators_lastname.java (Actual Java program)
PX_JavaOperators_lastname.txt (Copy of Java program)
PX_JavaOperators_lastname.png (Screen shot of program running)
PX_JavaOperators_lastname.mp4 (Video of you running the program)

// Decrement operators
