Java Application - Transfer ERC20 from one account to another account (no need for GUI)

Hi, I want a very simple running java application which will do the following: 1. accessing an accountA thru it's private key and password (or the credentials object in web3j) 2. get and list all available ERC20 tokens from accountA 3. send specific ERC20 token from accountA to accountB Example, accountA has the following tokens:: BNB, OMG, BAT, etc The 1st function "list" should list those tokens, for example: Available tokens and balance: BNB - 10 OMG - 5 BAT - 100 The 2nd function "send" should do the following: Input: Enter accountB address: 0x23s23433444.... ERC20 Token: OMG Amount: 5 Output: accountA transferred 5 OMG to accountB That's all. No need for GUI. What i need is only a running code for exploring
