Java code to interact with Hedera in TESTNET

Before you start

Accounts

Using your operator account and private (Set them in Accounts), create two other accounts for the participants and update the Accounts.java file. Use CreateAccount to create them

Deploy the contracts

Use DeployERC20 twice with the relevant token info (name, supply) and DeployDLOBEx for the main smart contract.
Note the deployment uses testnet and use your operator account.

Transfer some native HBARs to the participants

For the participants to be able to interact with the native chain, transfer some native HBARs to them using TransferHBARs.
You can then use CLI the with the option "Display balances" to confirm.

Transfer some tokens to the participants.

Same as above, but using TransferTokens

You should see on the CLI:

[main] INFO org.tj.hedera22.CLI - Displaying balances... (gas used: 320000)
[main] INFO org.tj.hedera22.CLI -  Operator: 9560.53196754 ℏ
[main] INFO org.tj.hedera22.CLI -  Participant 1: 200 ℏ, HHBAR Owned: 50000, HUSD Owned: 50000, HHBAR Allowance: 0, HUSD Allowance: 0
[main] INFO org.tj.hedera22.CLI -  Participant 2: 200 ℏ, HHBAR Owned: 50000, HUSD Owned: 50000, HHBAR Allowance: 0, HUSD Allowance: 0

Approve

The next step is to allow the smart contract DeployDLOBEx to spend your tokens post trade.
This is done with ApproveTransfer.

Finally, the last state from the CLI, you should also see the allowance:

[main] INFO org.tj.hedera22.CLI - Displaying balances... (gas used: 320000)
[main] INFO org.tj.hedera22.CLI -  Operator: 9552.52838234 ℏ
[main] INFO org.tj.hedera22.CLI -  Participant 1: 199.27539722 ℏ, HHBAR Owned: 50000, HUSD Owned: 50000, HHBAR Allowance: 50000, HUSD Allowance: 50000
[main] INFO org.tj.hedera22.CLI -  Participant 2: 199.27539722 ℏ, HHBAR Owned: 50000, HUSD Owned: 50000, HHBAR Allowance: 50000, HUSD Allowance: 50000
