To analyze this structure, you usually need to load the entire document and construct a hierarchy before you can do any work. Because it is based on information layers, Dom is considered to be tree-based or object-based. Dom and tree-based processing in the broad sense have several advantages. First, because the tree is persistent in the memory, you can modify it so that the application ca

want Masons silently for themselves, for the family for the future lay the groundwork. As you can see, string is a class that does not need to create a new object using new. It is immutable (Constant), and its value (like "ABC" is created, cannot be changed). Naturally, string actually implements the function of the sequence of the basic type char, so the Chinese name "string". Here it is possible to doubt that Mason will find the JDK source code evidence to show you: This code is from the JDK
