What a world-level method in Alice programming?

Alice methods are either world-level or class-level. Class-level methods operate upon a single character while world-level methods operate upon characters that interact with each other, such as when two characters are conversing with one another.


Which one executed first static block or static methods in java?

Static Blocks are always executed first. A static block is executed when your class is charged but a static method is executed only when is called, therefor first the class is charged and then is executed a method.


Difference between super and final keyword?

this is a reference to the current classsuper is a reference to the super class of the current class (the class from which this class extends). You can use super.super if you want to access the second level class. (The class your parent class extends) The purpose of having thisand super keywords is to differentiate between methods and variables in classes that may have the same name as that in the parent class. Under such situations if we want to ensure that only the methods from a particular class only gets called we can use this and super.


Are instence variable are global or local variable?

Instance variables are not global nor local variables.Variables in OOP are different from the counter parts in COBOL, FORTRAN, or C.To define any variable in OOP, it must be defined within a class/struct, at instance or class level (static in C# or shared in VB.NET).local variables usually referred to those defined within a method (of a class, instance-level or class-level) in OOP (object oriented programming).global variables, to define one in OOP is difficult and violate the object oriented design principle. However, the singleton design pattern does address this issue.Singleton pattern guarantees that the same instance (of that class) being the only one lives within your application (and globally accessible to that same instance), and hence the variables defined within this singleton may be treated as "global" variables

What is difference between instance variable and class variable in java?

The main difference between the class variable and Instance variable is, first time, when class is loaded in to memory, then only memory is allocated for all class variables. Usually static variables are called class variables. These variables are available throughout the execution of the application and the values are common to the class. You can access them directly without creating an object of the class. Instance variables are normal variables declared in a class, that would get initialized when you create an instance of the class. Every instance of the class would have a copy of the variable and you need a class instance (object) to access these variables


What is the explanation for the different access modifiers in Java?

An Access Modifier is a key word in java that determines what level of access or visibility a particular java variable/method or class has. There are 4 basic access modifiers in java. They are:PublicProtectedUnspecified (package-private)PrivateClasses can only be declared public or left unspecified (the "package-private" default level). Methods can be declared any of the above.See the Link on the Java Tutorial for a very good explanation of the various levels of access each modifier provides.

What are the advantages of a class in C over a structure in C?

A C struct only has public member variables whereas a C++ class combines member variables with member functions; the methods that operate upon the data. Moreover, each member of a class can be assigned a different level of access from public, protected or private access, thus limiting the member's exposure. This allows classes to hide data and implementation details from outside of the class, exposing only as much as is necessary in order to use the class. Thus the class becomes entirely responsible for the integrity of its data, while its methods act as the gatekeepers to that data.Note that in C++, a struct is exactly the same as a class, other than the fact that the members of a struct are public by default while members of a class are private by default, unless explicitly declared otherwise. Aside from that they operate in exactly the same way. In other words, a C++ struct is not the same as a C struct.
