java.lang.System

Synopsis

This class is a much smaller version of the J2SE System class, which provides static methods to access system functionality. The err and out streams represent their standard I/O equivalents. The getProperty() method returns a named property from the system properties list. (Note that the MIDP APIs redefine the microedition.locale property to include at least "MIDP-1.0“.)

The following list describes the characteristics of several properties.

microedition.platform

Name of the host platform/device (CLDC)

microedition.encoding

Default character encoding (CLDC)

microedition.configuration

Name/version of the configuration (CLDC)

microedition.profiles

Names of the supported profiles (CLDC)

microedition.locale

Current locale (MIDP)

The arraycopy() method is preserved from the J2SE System class; it copies a section of an array from a source to a destination. currentTimeMillis() returns the current time in milliseconds from the epoch, midnight GMT, January 1, 1970. The exit() method terminates the application with a status code. gc() performs a system-wide garbage collection.
