Stringis an immutable class in Java. An immutable class is simply a class whose instances cannot be modified. All information in an instance is initialized when the instance is created and the information can not be modified. There are many advantages of immutable classes. This article summarizes...
The implementation of string conversion is typically through the method toString, defined by Object and inherited by all classes in Java. Since: 1.0 See Also: Object.toString(), StringBuffer, StringBuilder, Charset, Serialized Form See The Java™ Language Specification: 15.18.1 String Concatenation...

在连接(Linking)步骤里头的解析(Resolution)阶段,需要将常量池中所有的符号引用(classes、interfaces、fields、methods referenced in the constant pool)转为直接引用(得到类或者字段、方法在内存中的指针或者偏移量,以便直接调用该方法) SymbolTable这个词在传统编程语言的实现里头比较常用(This data structure serves many...
