'class' or 'interface' expected?

Seems like you have a type-o just above line 13.  in your declaration of  the Matrix class.  should be a single c in the word 'class'.\n\nIf you aren't already, you may want to consider using an IDE like netbeans which will catch simple  syntax errors like this for you before compiling.\n\nhope this helps.

yes its a purely object oriented. Its because pretty much every variable youuse is and object. Even types like String and Integer. There are also many objects already written in java, that java provides, that you can use to create something or inheret it into your own classes and objects. \n\nThere are however some basic types like int (not Integer like above) and double, and boolean.  But majerity of the language is object oriented and almost every object is a subclass of another class. Thats why you end up having to do things like System.out.println. Meaning println is dependent on out, which intern dependent on System. So when writting something you end up having many dependecies and some lines can edn up being quite long.\n\nAnyways, yes, for majority - java is object oriented. Not completely since it still has basic types like int and double.

what about it \n\nmake the database  then make the interface ..

C) ABC, somthing1, something2 must be interface for the expression to be legal.\n\nThough java doesn't supports multiple inheritence for class, an interface can extend as many interface as needed. You can try compiling. But there is also a reason behind it.\nJava does not supports multiple inheritence because in diamond inheritence ( B and C extends A and D extends both B and C) it can cause ambiguity( as two copies of members of A would present in D).\nThis is not so for interface as there can't be ambiguity as all refer to same copy. So Java supports multiple inheritence for Inetrface

do you have java enabled?

You...cannot. Either declare it as a static variable, or create an instance of the object it is in.

Another tip - class names and file names are CASE SENSITIVE.  If you create a class "Apple", and refer to it as "apple", you won't find it at runtime.\n\n(I'm just beyond a novice at Java - hope this helps too - just vote for the other guy).

Have you tried getting the object as a FileInfo or something like that and then checking the type based on that?\nThats the best I can think of.

I think c is true becuse a varible name can not contain any thing other than lettera and digit if you add _ in letters.\nBut a class may not have constructor when default constructor will be used.

An abstract class can have instance methods that implement a default behavior. An Interface can only declare constants and instance methods, but cannot implement default behavior and all methods are implicitly abstract. An interface has all public members and no implementation. An abstract class is a class which may have the usual flavors of class members (private, protected, etc.), but has some abstract methods.

It usually should have called the constructor A() if you are making the object in maner "A a1;" in the main function. But also you have overloaded the operator "()". SO, it makes a confusion and actually none of the output from the above constructors are called. Another thing, its not a good thing to inital values in parameters. I've often faced these problems when I overloaded the "()" operator. For any further questions you can contact me.

your logic is there but i do not know your language and its syntax.  You should also post the error message. syntactical or logical.

all types in java are signed.  that's how it was designed.  i have found it to be a problem only very rarely.

Your object will be passed by reference because\nthat's how Java passes all objects.  Only the\nprimitive types like "int" are passed by value.

This doesn't sound like a problem with your compiler. Make sure you can open the file a:&#92;Firstprogram.asm without errors. I suspect there is a problem there.
