A. Only I and II.
B. Only II.

D. AIL
E. Only I.

Answer: C

NEW QUESTION # 218
Given the content of three files:

Which statement is true?

A. The B.java and C.java files compile successfully.
B. Only the A.Java file compiles successfully.
C. The A.Java and B.java files compile successfully.
D. Only the B.java file compiles successfully.
E. The A.Java and C.java files compile successfully.
F. Only the C.java file compiles successfully.

Answer: B

Explanation:
Class B doesn't compile because we can't use access modifiers (private) inside methods.
Class C doesn't compile because if the class is part of a package (p1), the package statement must be the first line in the source code file, before any import statements (java.io.*) that may be present.

NEW QUESTION # 219
Given:
public class MyClass {
public static void main(String[] args) {
while (int ii = 0; ii < 2) {
ii++;
System.out.println("ii = " + ii);
}
}
}
What is the result?

A. ii = 1 ii = 2
B. The program goes to an infinite loop outputting: ii = 1 ii = 1
C. The program prints nothing
D. The program goes into an infinite loop with no output
E. Compilation fails

Answer: E

Explanation:
The while statement is incorrect. It has the syntax of a for statement.
The while statement continually executes a block of statements while a particular condition is true. Its syntax can be expressed as:
while (expression) { statement(s) } The while statement evaluates expression, which must return a boolean value. If the expression evaluates to true, the while statement executes the statement(s) in the while block. The while statement continues testing the expression and executing its block until the expression evaluates to false.
