I am interested in interacting with a smart contract via a Java application. I found that there is a library called web3j (https://docs.web3j.io/) for which this should be possible, however there is not much documentation on how to install it.I expect that I should import Web3j with "import Web3j", but first I would have to install the package from the downloaded Git repository.

Events are a great way for backend (and frontend) services to be notified of smart contract changes and interactions in an asynchronous manner, as well a providing a cost effective way of storing data on the Ethereum blockchain that does not need to be consumed by a smart contract. As with many Ethereum interactions, the smart contract wrappers generated by Web3j are by far the simplest way to subscribe to, and process emitted events in your java backend.

By way of introduction I'm a lawyer who's been into cryptos for the last 4 years, and I'm looking to expand my knowledge on smart contracts by attending a beginner's programming course. The choice is pretty limited - it's either Java or C. There's also a Python course available, but it's targetted at "intermediate level programmers".

Ethereum for Java Developers Getting Started with Smart Contracts and the Solidity Language Using Web3J and Hyperledger Besu (Formerly Named Pantheon, Java Ethereum Client)

Ethereum. Smart Contract in ethereum is a piece of code that can be deployed and executed to perform business functions. The compiled code is run on every node using ethereum JVM.

It is Java library that allow the iteration of java application with contracts in the Ethereum network. It doesn't provide the capability to write contracts in java, but you can interact with contracts written in Solidity. It generates Smart Contract wrappers in Java from a Solidity compiled binary and ABI file. Ethereum Stack Exchange is a question and answer site for users of Ethereum, the decentralized application platform and smart contract enabled blockchain. It only takes a minute to sign up. Ethereum - Smart Contracts. There are several tools available to develop and test contracts. One of the simplest tools is provided on the official Ethereum site itself. The tool is called Remix, we will use this for our contract development. There an Ethereum standard, EIP-20 which started off as an Ethereum Improvement Proposal (EIP), that defines the standard functions that a smart contract providing tokens should implement. The EIP-20 standard provides function definitions, but does not provide an implementation example.
