All string literals in Java programs, such as "abc", are implemented as instances of this class. Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. For example: ...
自从Java发布以来,基本数据类型就是Java语言的一部分,分别是***byte, short, int, long, char, float, double, boolean***.当前前面我们也学习了基本类型的包装类,知道了每种基本类型都有它的包装类型,JAVA是面向对象的语言,很多类和方法中的参数都需使用对象(例如集合),但基本数据类型却不是面向对象的,这就...
