If anyone can also provide some good resource for such knowledge, that would b great for me.
Octal escapes are provided for compatibility with C, but can express only Unicode values \u0000 through \u00FF, so Unicode escapes are usually preferred.
377, surely? It should be in the Java® Language Specification (=JLS).

Where are you printing? The Windows® command line is notorious for being unable to render characters > 0x00ff, and even some “extended ASCII” characters come out oddly. For example £ is 0x00a3 but renders as ú on the command line. It has to do with the encoding used, which isn't Unicode but something beginning cp. If you haven't found anything really good to read about encodings, try Joel Spolsky.

That's where encodings come in.
The earliest idea for Unicode encoding, which led to the myth about the two bytes, was, hey, let's just store those numbers in two bytes each. So Hello becomes
00 48 00 65 00 6C 00 6C 00 6F
Right? Not so fast! Couldn't it also be:
48 00 65 00 6C 00 6C 00 6F 00 ?
Well, technically, yes, I do believe it could, and, in fact, early implementors wanted to be able to store their Unicode code points in high-endian or low-endian mode, whichever their particular CPU was fastest at, and lo, it was evening and it was morning and there were already two ways to store Unicode
