velmafxx/ShadowTool ? reverse-engineered prompt

Build me a simple Java tool for Tron that can generate random seed phrases and check the balance of a Tron address I enter.

I want it to have a clean, easy to use interface, let me paste or type an address, then show the balance clearly. It should also be able to generate secure passwords and handle sensitive info carefully.

Please make it runnable from the project as is, with sensible defaults and clear error messages if something goes wrong. If you need to look up current Tron library or API docs online, go ahead.
