Stringisimmutable, if you try to alter their values, another object gets created, whereasStringBufferandStringBuilderaremutableso they can change their values. Thread-Safety Difference: The difference betweenStringBufferandStringBuilderis thatStringBufferis thread-safe. So when the application needs to b...

A thread-safe, mutable sequence of characters. A string buffer is like a String, 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...
（1）StringBuilder的多线程不安全是指程序不能正常执行，即数组越界异常，而不是数据错乱问题。（2）Abs...
但是因为方法上没有synchronized关键字,所以StringBuilder多线程情况不安全 ,如果要在多线程环境下修改字符串,你到时候可以使用 ThreadLocal 来避免多线程冲突。 复制 publicclassThreadSafeStringBuilder{// 使用ThreadLocal为每个线程提供独立的StringBuilder对象privatestaticfinal ThreadLocal<StringBuilder>threadLocalStringBuilder=...

StringBuilder is not thread safe. So, it performs better in situations where thread safety is not required. StringBuffer is implemented by using synchronized keyword on all methods. StringBuffer /**/publicsynchronizedStringBuffer append(String string)/**/{/*197*/if(string ==null) string =String...
StringBuffer is thread-safe and synchronized whereas StringBuilder is not. That’s why StringBuilder is faster than StringBuffer. String concatenation operator (+) internally uses StringBuffer or StringBuilder class. For String manipulations in a non-multi threaded environment, we should use StringBuilder...
StringBuffer is mutable and thread safety as all the methods of this class are synchronized, so we should prefer to use it in multithreaded application StringBuilder is mutable but not thread safe as methods of this class are not synchronized, so we should prefer to use it in single ...
