As of JDK 1.1, the preferred way to do this is via the String constructors that take a java.nio.charset.Charset, charset name, or that use the platform's default charset. Java documentation for java.lang.String.String(byte[], int, int, int). Portions of this page are ...
String是C++、java、VB等编程语言中的字符串，用双引号引起来的几个字符，如"Abc","一天"。在java、C#中，String类是不可变的，对String类的任何改变，都是返回一个新的String类对象。 String 对象是 System.Char 对象的有序集合，用于表示字符串。String 对象的值是该有序集合的内容，并且该值是不...
