You are required to write a Java application program to determine and display the overall cost of a project. The overall cost of a project is made up of a fixed cost and a variable cost. Each project has a fixed cost of €10,000 and depending on the project category and the service type a variable cost is added. To determine the variable cost of a project, your program should accept a project category and a service type from the end user and depending on their values, determine the variable cost of the project based on the data in Table 1. A valid project category is one of 1, 2 or 3. If the user does not supply a valid project category an appropriate error message should be displayed and your program should end. The appropriate error message should be “Invalid project category: project category should be in the range 1 to 3“. If the user supplies a valid project category he/she should then be requested to enter a key service type. A valid service type is one of 1, 2 or 3. If the user supplies and invalid key service type an appropriate error message should be displayed and your program should end. The appropriate error message should be “Invalid service type: service type should be in the range 1 to 3“ If a valid service type is supplied then your program should determine the overall cost and display it.

Input Specification:

the project category and the service type .

Output Specification:

display the overall cost of a project.

Sample Input:

2
3

Sample Output:

Project cost is: 23500.0
