JDK自帶的工具可以方便的幫助我們處理一些問題，包括檢視JVM引數，分析記憶體變化，檢視記憶體區域，檢視執行緒等資訊。
我們熟悉的有java.exe,javac.exe,javap.exe(偶爾用),jps.exe,jmap.exe....等，下面會詳細介紹。分別在linux和windows下面介紹。windows與linux下面使用的都是JDK1.7.0_80
windows下的jdk版本如下:
$ java -version java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM)64-Bit Server VM (build 24.80-b11, mixed mode)
linux下的JDK版本如下:
[[email protected]_0_12_centos ~]# java -version java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
