The String class The String class contrasts with Character in that a String object stores a sequence of characters—a string—whereas a Character object stores one character. Because strings are pervasive in text-processing and other programs, Java offers two features that simplify dev...

The String class represents character strings. All string literals in Java programs, such as "abc", are implemented as instances of this class. 通过查看 API 的概述我们可以知道以下几点: String 是一个final修饰的类,不能被继承。 字符串字面量值"abc"也可以被看做是String对象。
All strings are now located in the heap, as most of other ordinary objects, which allows you to manage only the heap size while tuning your application. Technically, this alone could be a sufficient reason to reconsider usingString.intern()in your Java 7 programs. But there are other ...
