Since you didn't really specify what you are looking for, take a look at these System Properties:
由于您并未真正指定要查找的内容，请查看以下系统属性：
"java.vm.name""java.home""java.version""java.vendor""java.specification.vendor"
"java.vm.name""java.home""java.version""java.vendor""java.specification.vendor"
Like this:
像这样：
System.out.println(System.getProperty("java.vm.name"));
System.out.println(System.getProperty("java.home"));
System.out.println(System.getProperty("java.vendor"));
System.out.println(System.getProperty("java.version"));
System.out.println(System.getProperty("java.specification.vendor"));

There are two kind of JVM names namely:
有两种JVM名称，即：
- Java Virtual Machine implementation name : Java HotSpot(TM) Client VM
- Java Virtual Machine specification vendor : Oracle Corporation
- Java 虚拟机实现名称：Java HotSpot(TM) Client VM
- Java 虚拟机规范供应商：Oracle Corporation
Type code in java program and see output:-
在java程序中输入代码并查看输出：-
System.out.println("Java Virtual Machine specification version : "+System.getProperty("java.vm.specification.version"));
System.out.println("Java Virtual Machine specification vendor : "+System.getProperty("java.vm.specification.vendor"));
System.out.println("Java Virtual Machine specification name : "+System.getProperty("java.vm.specification.name"));
System.out.println("Java Virtual Machine implementation version : "+System.getProperty("java.vm.version"));
System.out.println("Java Virtual Machine implementation vendor : "+System.getProperty("java.vm.vendor"));
System.out.println("Java Virtual Machine implementation name : "+System.getProperty("java.vm.name"));

To know ur JVM vendor:
type java -versionin cmd and see third line of it.
要了解您的 JVM 供应商：输入java -versioncmd 并查看它的第三行。
eg:
例如：
C:\Users\Hyman>java -version
java version "1.8.0_74"
Java(TM) SE Runtime Environment (build 1.8.0_74-b02)
Java HotSpot(TM) Client VM (build 25.74-b02, mixed mode)
C:\Users\Hyman>java -version
java版本“1.8.0_74”
Java(TM) SE 运行时环境（构建 1.8.0_74-b02）
Java HotSpot(TM) 客户端 VM（构建 25.74-b02，混合模式）
