The functionality ofStringBufferandStringBuilderare very similar. They both represent a mutable sequence of characters that can be manipulated and accessed using various methods. However, they also have some significant differences and trade-offs that make them suitable for different use cases: StringBuf...
StringBuffer是同步的,StringBuilder不是。 StringBuilder比StringBuffer更快,因为它没有synchronized。 这是一个简单的基准测试: publicclassMain{publicstaticvoidmain(String[] args){intN =77777777;longt; { StringBuffer sb =newStringBuffer(); t = System.currentTimeMillis();for(inti = N; i -->0;) {...
public static void main(String[] args) { StringBuffer sBuffer = new StringBuffer("这里面可添加值:"); sBuffer.append("one"); sBuffer.append("two"); sBuffer.append("three"); System.out.println(sBuffer); } } 1. 2. 3. 4. 5. 6. 7. 8. 9. 总结:1.StringBuilder:适用于单线程下...
Although, StringBuilder and StringBuffer classes can be used for mutable sequences of characters in Java, they have a key difference. Unlike StringBuffer class, StringBuilder class is not thread-safe, and provides no synchronization. Therefore, it is recommended that the StringBuilder class should be...
