Summary
No summary available for this chapter.
Concept Check
0/10
In Java, why might if-else be preferred over switch for checking grade ranges?
Less code needed
Faster execution
Requires exact values
Handles ranges easily
What happens if no case matches in a switch statement for grades?
Skips the statement
Loops indefinitely
Throws an exception
Executes default if present
Can switch statements in Java handle integer ranges like 90-100?
Yes, with conditions
Depends on compiler
Yes, directly
No, only exact values
In the transcript's program, how is user input for grades obtained?
Using Scanner class
Via System.in directly
With BufferedReader
Through file input
What is a limitation of switch compared to if-else in Java grading?
No range checking
Better performance
More concise code
Handles strings easily
What happens in a switch if no case matches?
Skips to next statement.
Executes default block if present.
Does nothing.
Throws an exception.
Can switch statements use String variables?
No, only integers.
Yes, but not recommended.
Yes, since Java 7.
Only with enums.
In if-else, what if multiple conditions are true?
Last block executes.
All blocks execute.
It throws an error.
Only first true block executes.
What is fall-through in switch statements?
Skips to default.
Exits the switch.
Executes next case without break.
Loops back to start.
Which is faster for many conditions?
Switch for integral types.
If-else always.
Depends on input.
They are equal.
