Difference between ASP and ASP.NET

SP stands for Active Server Pages. ASP.NET is the next generation of ASP. After the introduction of ASP.NET, old ASP is called 'Classic ASP'.

Classic ASP uses vb script for server side coding. Vb Script is not supported any more in ASP.NET. Instead, ASP.NET supports more languages including C#, VB.NET, J# etc. VB.NET is very similar to vb script, so it should be easy for old Visual Basic or ASP programmers to switch to VB.NET and ASP.NET

Object -Interview Questions

Object concepts

Q: What is an object in Java?

A: In Java the Object class is the ultimate superclass of every other object type. All objects are extended from the Object class, either directly or by inheritance through any number of parent classes. If a class does not explicitly extend any named class, it implicitly extends the Object class. An object with a small o is the word used to describe an instance of a Java class.

MODIFIERS -INTERVIEW QUESTIONS

Q: How can I prevent inheritance without marking a class final?

A: Declaring a class final is the simplest way to prevent extension. A more limited way to control overrides without preventing extension is to declare individual methods final. If all methods are declared final but not the class, the class may be extended but none of its methods overridden.

5. What’s the top .NET class that everything is derived from?
System.Object.
