Whats the best approach?

[umar hathab]

Hi,
I have one method which does some operations depending on a flag.I have to call this method from another method.But I already know the value of flag before calling the method.So I want to know which is the best way?should i call the method if the flag is true? or i should put the flag condition inside the method and call that method anyway?
the code may be like this?
1.Approach1.
boolean flag=false;
public void manage()
{
flag=true//some operatins
doSome();
}
public void doSome()
{
if(flag)
{
//do some thing...
}
}
2.Second approach
1.Approach1.
boolean flag=false;
public void manage()
{
if(flag)
{
doSome();
}
}
public void doSome()
{
//do some thing...
}
can u tell me the performance issues with both the approch...Question may seem silly..but I am eager to know..
Thanks..

Theoretically, putting the check before the method call will be faster.
Practically, you probably wouldn't notice the difference. A modern Hotspot engine might even decide to inline the method call, so there wouldn't be any difference at all!
So, you shouldn't care about performance, but about maintainability!
