The DefaultEnvironment implements the Environment interface using the JDK class java.lang.System .

A Environment object is a substitute for the usual environment as defined in the java.lang.System class, most important the stdin and stdout channels java.lang.System.in and java.lang.System.out .

Environments are especially useful in classes that can be used both standalone (having a main method) or in an application where the class is only one of many.

The EnvironmentProvider is a singleton object to store and provide Environment instances.

This is the test suite for the java package tree.

This class tests the functionality of the ThrowableList interface through various implementing classes.

This interface should be implemented by classes derived from java.lang.Throwable that may contain a stacked, additional or wrapped throwable.

Such cases are common when

• a method implements a certain interface method that allows for a specific throwable like IOException, but the method itself may encounter a different throwable type like SQLException (wrapped throwable)
• one application layer catches an throwable only to add its specific information in form of another throwable (throwable stack, nested throwable like in SQLException or MessagingException).

We provide the expected code in block comments starting with -->, terminated by -->.

This class is used by the implementations of the ThrowableList interface.
