size() and get() are indeed non-static methods from AbstractList. list.size() and l.get() work because they are correctly being invoked from an AbstractList instance (list and l). That instance is provided as an argument to the constructor of SubList and then stored in a private field of the class: private final AbstractList<E> l; […] SubList(AbstractList<E> list, … Read more
You can get the select node and find all the options in the select node and get the html from those options. var selectNode = $(‘select-selector’); var options = selectNode.find(‘option’).toArray().map(function (o) { return o.outerHTML}); Edit as per suggestion from comment by Rory. $.map(selectNode.find(‘option’), function(o) { return o.outerHTML; }); 1 solved How to get all the … Read more

/^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?:[a-zA-Z0-9]{8,})$/ (click for diagram) I assumed you meant at least 8 characters. If not, then you need {8} (exactly 8) instead of {8,} (at least 8) I assumed “no special characters” means only alphabetic and numeric characters, [a-zA-Z0-9] if any other characters are to be allowed, then you can add them here.

Next is the code for the “for” statement converted into assembler, register EDI is used as the control variable “i”, if EDI is been changed by “encrypt21”, just push it before and pop it after “call encrypt21” to preserve-restore its value. I changed the parameter “length” by “len” because the name gave me problems : … Read more
That’s because although you call the function you don’t save its return value anywhere. Try instead def main(): price = equation(5, 10) print(price) Note also that the variable in the calling function doesn’t need to relate to naes inside the called function (which are generally only available inside the function). So you could equally well … Read more

Would overriding func1 work? class Class(file1.Class2): def func1(self): print “Class3.func1” c = Class3() c.func2() Since func2 is not defined in Class3, Class2.func2 is called. However, in the body of that function, self is still an instance of Class3, so self.func1() calls Class3.func1, not Class1.func1. That is different from d = Class2() d.func2() where self in … Read more
