you can get source code from binary these days. Although the source code obtained by Java's bytecode is more readable, obfuscating will make it slightly unreadable. Its not that only Java can be reverse engineered to code. Even C/C++ these days (with Hexrays plugin for IDA Pro) can be decompiled to source. Obfuscaters will make it hard to read but not impossible. There is nothing that can save your program from an intelligent and capable reverse engineer. :).

Good luck.

Decompiler Bytecode and Obfuscators
I need to find a differential equation $x'=f(x)$ that has three equilibrium points that are


all sinks;
all sources.


So two differential equations total. Help!
