<代码不换行不写indentation,把所有东西敲在一块>:虽然代码读起来非常费劲,但是不影响输出结果,因而只是bad style,没有任何syntax error。 //The main method of the Lipogram class, unreadable but compiles fine public static void main(String[] args) {Scanner scanner = new Scanner (System.in);String a...

In this example, the class AverageProgram (which is the program) contains only one method (function), main(). Notice that much of the syntax is the same as C or C++, including comment delimiters: you can use either C (/* */) or C++ (//) style delimiters in Java. Even the while...

While JavaParser generates an Abstract Syntax Tree, JavaSymbolSolver analyzes that AST and is able to find the relation between an element and its declaration (e.g. for a variable name it could be a parameter of a method, providing information about its type, position in the AST, ect)....
First, we've added the parameters using a syntax that superficially looks like method declarations: value(), owners(), and priority(). As you'll see in my next article, these methods act as getters than can be called at runtime. The "value" parameter, because of its special name, ...
symbolic type descriptor. As usual, the Java compiler emits aninvokevirtualinstruction with the given symbolic type descriptor against the named method. The unusual part is that the symbolic type descriptor is derived from the actual argument and return types, not from the method declaration. ...
