我想测试某些代码块的运行时间如下:
start = System.currentTimeMillis(); { ... this.dosomething(); } end = System.currentTimeMillis(); System.out.println(end - start);
当我优化代码块时,如何注释那些快速计算时间的代码,如下所示?
//start = System.currentTimeMillis(); { ... this.dosomething(); } //end = System.currentTimeMillis(); //System.out.println(end - start);
