Methods

`atLeast(JavaVersion)`	Tests whether this version of Java is at least the version of Java passed in.
`atMost(JavaVersion)`	Tests whether this version of Java is at most the version of Java passed in.
`toString()`	The string value is overridden to return the standard name.
`valueOf(String)`
`values()`

public boolean atLeast(JavaVersion requiredVersion)[source]
