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");
}

Q: 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"); }

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.
