Implementation

• Install Mockito for Maven.

• Test that mocks a web3j instance.
• Added an entry in .gitignore for Eclipse IDE files.
• Create defaultTx class and test.
• .gitignore IDE specific files.

Files

Considerations

For defaultTx class #19 :

• (Initial) The address instance is of data type byte[20] (20 bytes for address) to save space, but web3j provides the Bytes32 object as well. Not sure which direction would be best.

• (Current) Used the java contracts as a reference and set as String.

• (Initial) I initially set the gas and gasPrice instances as java.lang.Number. That way you can set their types as either Double or Float wrapper classes to port the original TS advanced types [string | number | BN]. But the documentation advises using java.math.BigDecimal for currency and have refactored.

• (Current) Used the java contracts as a reference and set as BigInteger.

Seems like new linked issues after the initial pr are not linked and have to be manually done.
