Every array also belongs to a class that is reflected as a Class object that is shared by all arrays with the same element type and number of dimensions. The primitive Java types (boolean, byte, char, short, int, long, float, and double), and the keyword void are also represented as ...
Class.forName(name, initialize, loader)带参函数也可控制是否加载static块。并且只有调用了newInstance()方法采用调用构造函数,创建类的对象 7. Java7、Java8的新特性(baidu问的,好BT) java7有一些比较重要的更新,如异常处理增加了被抑制的异常、捕获多异常、try-with-resource自动释放资源等,还有应用了G1垃圾回收...

上述代码片段是经过精简的libinstrument中Agent_OnLoad实现的,大概的流程就是:先创建一个JPLISAgent,然后将ManiFest中设定的一些参数解析出来, 比如(Premain-Class)等。创建了JPLISAgent之后,调用initializeJPLISAgent对这个Agent进行初始化操作。跟进initializeJPLISAgent看一下是如何初始化的: ...
-F force. Use with -dump:<dump-options> <pid> or -histo to force a heap dump or histogram when <pid> does not respond. The "live" suboption is not supported in this mode. -h | -help to print this help message -J<flag> to pass <flag> directly to the runtime system ...
