If I have a class which all the functions in it need to pass a check first, which of the following is more preferred
1.
class check{
public check(Status){
if(CheckFunc(Status)){
// Passed the Check function and return a class instance
return new UpdateClass();
}
}
class UpdateClass{
public void Func1(){
// Do the stuff
}
// Other functions...
}
OR
2.
class UpdateClass{
boolean passedCheck = false;
public UpdateClass(Status){
if(checkFunc(Status)){
this.passedCheck = true;
}
}
public void Func1(){
if(this.passedCheck){
// Do the stuff
...
}
}
// Other functions...
}
Also, is it a good way to use a class/function to decide which class to be instantiated?
for example:
public Animal decideWhichClass(Status){
if(Status == StatusA){
return new Dog();
}
else if (Status == StatusB){
return new Cat();
}
}
Animal a = decideWhichClass(CurrentStatus);
