System.out.println("Time needed for 50000 StringBuilder appends: " + (System.currentTimeMillis() - timerStarted) + "ms"); 如上打印输出因Java虚拟机而异,从如上基准测试中我们还是可以看出StringBuilder是字符串操作中最快的,次之StringBuffer,它比StringBuilder慢1倍多,最后是String这是字符串操作中最慢的...

Jasminbytecode是一种基于Java字节码的汇编语言,用于生成Java字节码文件。在Jasminbytecode中,goto指令用于无条件跳转到指定的代码行。然而,这个问题中提到Jasminbytecode缺少goto指令的参数。 在Jasminbytecode中,goto指令需要一个标签作为参数,用于指定跳转的目标位置。这个标签通常是在代码中定义的,可以是一个标识符或者...
Similarly, in therunmethod of theReadThreadclass, a constructor is defined; it initializes the name and the list. Therunmethod has the actualreadlogic. TheStringBuilderclass gets used to make manipulations in the output. Theappendmethod appends the output found in the write thread class with th...
