- Method Detail
  - describePlatform
```
public static String describePlatform()
```
    Describes the platform. Outputs Java version and vendor.
    
    Returns:
    
    Description of the current platform
  - isThisJVM
```
public static boolean isThisJVM(String name)
```
    Check if the current JVM is of the type passed in parameter. Normally, this will be a constant from this class. We basically do System.getProperty("java.vm.name").startWith(name).
    
    Parameters:
    
    name - jvm name we are looking for
    
    Returns:
    
    if it's the requested JVM
  - isAndroidOpenJDK
```
public static boolean isAndroidOpenJDK()
```
    Check if this JVM is an Android JVM based on OpenJDK.
    
    Returns:
    
    if it's an Android version based on the OpenJDK. Will return false if this JVM isn't an Android JVM at all
  - isAfterJigsaw

public static boolean isAfterJigsaw()
```
    Tells if the current JVM is running Java 9 or above
    
    Returns:
    
    if the current JVM is Java 9 or above
  - isAfterJava11
```
public static boolean isAfterJava11()
```
    Tells if the current JVM is running Java 11 or above
    
    Returns:
    
    if the current JVM is Java 11 or above
  - isGoogleAppEngine

@Deprecated
public static boolean isGoogleAppEngine()
```
    Deprecated. No need to differentiate GAE anymore since they have stopped using a security manager
