StringBuilder 类在 Java 5 中被提出,它和 StringBuffer 之间的最大不同在于 StringBuilder 的方法不是线程安全的(不能同步访问)。 由于StringBuilder 相较于 StringBuffer 有速度优势,所以多数情况下建议使用 StringBuilder 类。然而在应用程序要求线程安全的情况下,则必须使用 StringBuffer 类。 三者的继承结构 三者的...
Appendable:An object to which char sequences and values can be appended. 数据结构 String final 型byte数组,不可修改性的源头。 StringBuffer、StringBuilder 在java.lang.AbstractStringBuilder中: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 /** * The value is used for character storage. */ ...
StringBuilder具有较高的性能和效率,并且是线程不安全的,适用于单线程环境下的字符串处理。 二. 区别: 1. 不可变性: String类是不可变的,一旦创建就不能被修改。任何对字符串的操作都会创建一个新的字符串对象。 StringBuffer和StringBuilder类是可变的,可以在原始字符串上进行修改,无需创建新的对象。 2. 线程安...
