IF inside try block

I want to execute my method callmethod if the condition inside the IF statement is met. Else it should execute the catch block. But during implementation, if the condition is not met, it does not go to the catch block.

try{
if(count==0)
callmethod();
}
catch (Exception e){
System.out.println(e);
}

This is a good application for methods:

try {
  if (count == 0) {
    callOneMethod();
  }
  else {
    callOtherMethod();
  }
catch (Exception e) {
  callOtherMethod();
}

That way you don't have any duplicated code and you're not doing weird things with exceptions in non-exceptional cases.

Since you are trying to hit the catch block, you need to throw an exception if your parameter is not met (i.e. count != 0).

Example:

try {
    if(count==0){
        callmethod();
    } else {
        throw new SomeException("some message");
    }
}
catch (Exception e){
    System.out.println(e);
}
