Discussion Forum : Flow Control - Finding the output (Q.No. 13)
13.
What will be the output of the program?
Float f = new Float("12");
switch (f)
{
case 12: System.out.println("Twelve");
case 0: System.out.println("Zero");
default: System.out.println("Default");
}
Answer: Option
Explanation:
The switch statement can only be supported by integers or variables more "narrow" than an integer i.e. byte, char, short. Here a Float wrapper object is used and so the compilation fails.

Switch Statement allows "String" since Java 7. :)

Switch statement can take Wrapper object also,but compilation fails because of Float Wrapper class.
We can't take Float, Double Wrapper classes like float primitive data type float double.

From java 7 onward we can use string inside switch.

Argument of float is string & value provided by switch is integer. That's why it is throwing error. Please correct me if I understood wrongly.
