Why java is a middle level language.

I do not understand why java is not a high level language it is a middle level language.Someone please explain me the difference between Low level language,Middle Level language and High Level Language.

If you don't understand what the difference is, then how do you know it's a 'middle level' language? WHO says so?

I have not heard these terms before, so I can't answer you question in any case.

Ashok,
See this thread for why C is a "middle level language." The same reasons apply to Java.

At the risk of having to send myself to intermediate, does the same actually apply to Java as to C? Java does not (as C and C++ do) allow direct manipulation of pointers.

I though it was

1st generation = machine code

2nd generation = assembly mnemonics

3rd generation = algebraic-like formulae

4th generation = use instructions as functions, rather the way SQL does.

the programming language terms "low/middle/high level" and "generation" are mostly used by those who think their language is "better", higher, more evolved.

they in a general way apply to when the main concepts associated with the language first arose as concepts in Computer Science, and as such are vaguely useful in determining the relative age of a language,

ergo, Java is mid-level and 3GL because it's been around for a while, and things have come along since it was born - it's concepts not much different from C,C++,Objective-C (the latter crudely being the source of it's initial class library)

In addition to Campbell's list of 4

5th generation = constraint-based programming

From Wikipedia (which has reasonable coverage of basic computer science concepts):
1GL / 2GL / 3GL / 4GL / 5GL
