switch

[meena latha]

public class call1
{
public static void main(String[]arg)
{
static final int i =9;
switch(i)
{
case i:System.out.println("wel");
case 3:
default:
}
}
}

Why this program gives compile time error.
Stating illegal start of expression .

U cant have static variable inside a static method
The variable i is declared to be static final
Thats why i guess its a compiler error.

i don't think you can declare a static variable inside a method. move it outside of the main method, and it compiles.

[Trevor Whitehead]

local variables can only be marked final

[meena latha]

Thanks to all.Yes local variable can be marked only final.

Why did the Java Designers didnt allow static variables in static methods. If i want that variable value persist across different calls to the method and at the same time hide the variable from other methods in the class , there is no way out in java.

Please clarify the design issue involved... i guess they didnt want the method to maintain any state of its own. am i right ..


thanks for reading

There is no concept of hiding between members of the same outer enclosing class.

If you look at the rules for inner classes, you will see what I mean.
