In Perl,\1through\9are always interpreted as back references; a backslash-escaped number greater than9is treated as a back reference if at least that many subexpressions exist, otherwise it is interpreted, if possible, as an octal escape. In this class octal escapes must always begin with a...
A backslash may be used prior to a non-alphabetic character regardless of whether that character is part of an unescaped construct. Backslashes within string literals in Java source code are interpreted as required by The Java Language Specification as either Unicode escapes (section { Added in 1.4...
一、String实现源码分析 1、String的定义 复制 publicfinal class String implements java.io.Serializable, Comparable, CharSequence 1. 从上,我们可以看出几个重点: String是一个final类,既不能被继承的类 String类实现了java.io.Serializable接口,可以实现序列化 ...
