QUESTION NO: 1
Given the code fragment: What is the result?
A. Found Red
B. Found Red Found Blue
C. Found Red Found Blue Found White
D. Found Red Found Blue Found White Found Default
Answer: B
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.
