What I did when I explored was make simple examples like those I’m presenting: Try the simplest version with the least parameters. That will usually be the easiest to understand. Once you get that working look at the implementation. Often the simpler one will be passing its own ‘default...
4.3. Default Values and Actions A typical pattern in programming is to return a default value if we determine that the result of an operation isnull. In general, we can use theternary operator; but withOptional, we can write the code as below: Optional<Company>companyOptional=Optional.empty(...
