1.'Java is platform-independent'- - What's that supposed to mean though the Java run-time package differs from platform to platform;almost similar to creating different compiler for every different machine for the purpose of executing a C/C++ program?
2.'a machine is big-endian'-what does the statement signify?
3.As the Unix OS is entirely made up of C prog.language,is there any OS entirely made up of Java?
4.What do you mean by 'text-based, console programs'?
5.Why is it necessary to enclose every method in a class or interface in JAVA?

yet you can program low-level parts with c/asm then wrap them with java... it is much easier to write on top of windows or linux, which already did write these low-level parts...

a method is meaningless if it is not belong to an object or class. •

This looks a lot like homework, but what the hell....
There was JavaOS by Sun, but it's already considered legacy. Pretty much a microkernel with a JVM looks like. There's also an open-source project JNode. So yes, it's possible. No, it's not common and likely never will be.
