You can start by looking at the date. Anything made before 1923, no matter what, will be definitely in the public domain. ...

If it stores any type of objects mixed, use Object as storage class. All classes inherit from Object and for primitives use their respective wrapper classes. Or just use one of the bazillion container classes that already exist.
The answer is (data) abstraction!
Hope it helped (:

Answer:
c) 4.4
Explanation:
You can evaluate step by step the code. You know tha your input is 4.0
Step 1 Variables definitions:
double tax;
double total;
Step 2 Ask the user for the input:
System.out.print("Enter the cost of the item");
Step 3 read de input:
total = scan.nextDouble();
Step 4 evaluate the condition ( is the input greater or equal than 3.0 ? [True])
if ( total >= 3.0)
Step 5 get done the operations inside the condition and print it:
tax = 0.10;
System.out.println(total + (total * tax));
