Next, let’s read a text file into tokens using a StreamTokenizer. The way the tokenizer works is – first, we need to figure out what the next token is – String or number; we do that by looking at the tokenizer.ttype field. Then, we’ll read the actual token based on this type...

When we set up our build file, we need to make sure to bundle each module in our project as a separate jar. 在构建各个模块确保项目每个模块都可以捆绑为单独的jar包。 3. Default Modules When we install Java 9, we can see that the JDK now has a new structure. ...
This strategy provides good support for polymorphic relationships but requires one or more join operations to be performed when instantiating entity subclasses. This may result in poor performance for extensive class hierarchies. Similarly, queries that cover the entire class hierarchy require join operatio...
