• to generate Java code from Solidity smart contract you need to have solc compiler and web3j generator
  solc <contract>.sol --bin --abi --optimize -o <output-dir>/
web3j solidity generate /path/to/<smart-contract>.bin /path/to/<smart-contract>.abi -o /path/to/src/main/java -p com.your.organisation.name
