We must determine then how to represent meaningful information (such as a name or a program instruction or an image) in binary. 2. Java is an object-oriented programming language. ANS: T Java is classified as a high-level programming language but it is also classified as an object-oriented programming language because it allows the programmer to implement data structures as classes. 3. System.out.print is used in a program to denote that a documentation comment follows. ANS: F Documentation comments follow // marks or are embedded between */ and */.

ANS: F Neither Java source code nor Java byte codes are executable. Both must be compiled or interpreted into machine code. Java byte codes are useful however in that they are machine-independent but semi-compiled code that allows your Java code to be transmitted over the Internet and executed on another computer even if that other computer is a completely different type. 5.
