Question

I have to use a value, typically return via a method in switch case.

int getVal(){return 121;}

 switch(expr){

    case getVal():
 }

But its giving comilation error: constant expression required.

I also tried like,

int _val = getVal();

 switch(expr){

    case _val:
 }

Having same result.

Is there any workaround to implement it.

Thanks,
Amit

As the error clearly states, switch only works with constant expressions.

You need to use an if.
