NEW QUESTION # 126
Given the code fragment:
What is the result?
- A. Found Red Found Blue Found White Found Default
- B. Found Red Found Blue Found White
- C. Found Red
- D. Found Red Found Blue
Answer: D
Explanation:
As there is no break statement after the case "Red" statement the case Blue
statement will run as well.
Note: The body of a switch statement is known as a switch block. A statement in the switch block can be labeled with one or more case or default labels. The switch statement evaluates its expression, then executes all statements that follow the matching case label.
Each break statement terminates the enclosing switch statement. Control flow continues with the first statement following the switch block. The break statements are necessary because without them, statements in switch blocks fall through: All statements after the matching case label are executed in sequence, regardless of the expression of subsequent case labels, until a break statement is encountered.

- A. static
- B. public
- C. volatile
- D. local
- E. synchronized
Answer: A,B
Explanation:
B: A class can be declared as public or private.
C: You can declare two kinds of classes: top-level classes and inner classes.
You define an inner class within a top-level class. Depending on how it is defined, an inner
class can be one of the following four types: Anonymous, Local, Member and Nested top-level. A nested top-level class is a member classes with a static modifier. A nested top-level class is just like any other top-level class except that it is declared within another class or interface. Nested top-level classes are typically used as a convenient way to group related classes without creating a new package. The following is an example:
public class Main { static class Killer {

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.
