JDK的功能:

  JDK是 Java 语言的软件开发工具包,主要用于移动设备、嵌入式设备上的java应用程序。JDK是整个java开发的核心,它包含了JAVA的运行环境(JVM+Java系统类库)和JAVA工具。

JDK(Java Development Kit) 是 Java 语言的软件开发工具包(SDK)。
SE(JavaSE),standard edition,标准版,是我们通常用的一个版本,从JDK 5.0开始,改名为Java SE。
EE(JavaEE),enterprise edition,企业版,使用这种JDK开发J2EE应用程序,从JDK 5.0开始,改名为Java EE。从2018年2月26日开始,J2EE改名为Jakarta EE [1] 。
ME(J2ME),micro edition,主要用于移动设备、嵌入式设备上的java应用程序,从JDK 5.0开始,改名为Java ME。
没有JDK的话,无法编译Java程序(指java源码.java文件),如果想只运行Java程序(指class或jar或其它归档文件),要确保已安装相应的JRE。
