toStrings

public static java.lang.String[] toStrings(java.util.Map environment)

Get the variable list as an array.

参数:

environment - the environment to use, may be null

返回:

array of key=value assignment strings or null if and only if the input map was null

public static java.util.Map getProcEnvironment()
                                        throws java.io.IOException

Find the list of environment variables for this process. The returned map preserves the casing of a variable's name on all platforms but obeys the casing rules of the current platform during lookup, e.g. key names will be case-insensitive on Windows platforms.

a map containing the environment variables, may be empty but never null

抛出:

java.io.IOException - the operation failed
