clarification needed for ecj and gcj

[Yao]

Hi, everyone,
I am a newbie in java development, and I am confused by "ecj" and
"gcj". I searched in google by the keywords "ecj gcj", but I get
little useful information, so I ask help here.

AFAIK, ecj is the short form of Eclipse Compiler for Java, and gcj is
Gnu Compiler for Java. Are both of them are java compilers? What is
the difference between them?

From the result of google search, I am confused by some items, such as

"eclipse-ecj-gcj".

Any comments are appreciated and thanks in advance!

ecj compiles to bytecodes, and gcj can compile from either java sources
or bytecodes to native binary code.

"eclipse-ecj-gcj".

I think that's ecj compiled down to native code, so that it potentially
runs faster.
