Information: Java Script There are two types of accounts - S for short term contract and L for long term contract. 3.1 Create an Employee objects project. Create an Employee class and use the provided UML diagram to code the instance fields, constructors and methods. 3.1.1 Both constructors must increment the static numberOfEmp field by one. Both constructors must call the setEmpCode() method to compile a code for the employee. Both constructors must call the setCommission() method. 3.1.2 setEmpCode() method: The empCode must be constructed in the following way: First character is the type of contract Next three characters a random 3 digits Add a backslash and the number of objects value to the code NOTE: You have to use the Random class in your code (See Ch 9). Do NOT use the Math.random() method. Example of code: S781/1 Explanation: Short term contracts (S), 781 is the 3-digit random value, first employee object. 3.1.3 setCommission() method: Assign a basic amount to the…
