Assume the following:
private static boolean A() { int parsedUntil = 0; ... ... ... }
Is parsedUntil considered to be a static variable? I noticed that I can't declare it as static inside this static function.
Follow-up question: I read that a static variable will only be initialized once. Does that mean the first time I call function A() the value will be set to zero, but every other time I call A(), that row is omitted?
Local variables in static methods are just local variables in a static method. They're not static, and they're not special in any way. Static variables are held in memory attached to the corresponding Class objects; any objects referenced by static reference variables just live in the regular heap.
A static method can only access static data members and static methods of another class or same class but cannot access non-static methods and variables.
Class variables also known as static variables are declared with the static keyword in a class, but outside a method, constructor or a block. There would only be one copy of each class variable per class, regardless of how many objects are created from it.
In Java, a static variable is a class variable (for whole class). So if we have static local variable (a variable with scope limited to function), it violates the purpose of static. Hence compiler does not allow static local variable.
No, it's not a static variable. It's a local variable. Any variable declared in a method is a local variable. If you want a static variable, you have to declare it outside the method:
private static int parsedUntil = 0;
There's no way of declaring a static variable which can only be used within a single method.
no, A()
is a static method, and parsedUntil
is a local variable inside A.
Modifiers like static
are not valid in local variables (only final
is permitted afaik)

true
Does that mean the first time I call function A() the value will be set to zero, but every other time I call A(), that row is omitted?
since parsedUntil is not a static field, but a local variable in a static method, this is not the case.
