but can be modified. At any point in time it contains some particular sequence of characters, but the length and content of the sequence can be changed through certain method calls. String buffers are safe for use by multiple threads. The methods are synchronized where necessary so...
2. StringBuffer 源码中注释 * A thread-safe, mutable sequence of characters.*A string buffer is like a {@link String}, but can be modified.*The principal operations on a {@code StringBuffer} are the*{@code append} and {@code insert} methods, which are*overloaded so as to accept data...
2.String类的方法 String类可以说是一个宝藏,每一个方法都是那么重要,是我们编程过程经常会遇到会使用的一个类,看看String类提供的方法 Method Summary Methods inherited from class java.lang.Object clone,finalize,getClass,notify,notifyAll,wait,wait,wait 3.StringBuffer类的方法 Method Summary Object clone...
和String 类不同的是,StringBuffer 和 StringBuilder 类的对象能够被多次的修改,并且不产生新的未使用对象。 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 (introduced in Java 5) is identical to StringBuffer, except its methods are not synchronized. This means it has better performance than the latter, but the drawback is that it is not thread-safe. Read tutorial for more details. Share Improve this answer Follow edited Jan 14,...
Returns a string representing the data in this sequence. void trimToSize() Attempts to reduce storage used for the character sequence. Methods inherited from class java.lang.Object clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait Methods inherited from interface ...
String buffers are safe for use by multiple threads. The methods are synchronized where necessary so that all the operations on any particular instance behave as if they occur in some serial order that is consistent with the order of the method calls made by each of the individual threads invo...

Whereas, StringBuffer class and its methods are thread-safe.Which class is better to use StringBuffer or StringBuilder?Both of the classes have their advantages and disadvantages. In general, it is better to use the StringBuilder class because the StringBuilder class is faster than StringBuffer....
