Training Program Details
Java 2 -- Advanced java.lang & java.util Packages
The first unit describes the important methods in the System class, such as arrayCopy( ), exit( ), gc( ), getProperty( ), load( ), setProperty( ), setIn( ), setErr( ), and loadLibrary( ). You will learn how the System class provides access to standard input and output streams. The unit also explains the methods in the Process class, such as destroy( ), exitValue( ), waitFor( ), getErrorStream( ), getInputStream( ), and getOutputStream( ).
You will also learn about the Runtime class and use the Runtime class methods, such as totalMemory( ), load( ), getRuntime( ), freeMemory( ), exec( ), and exit( ) in a program. Finally, you will learn to perform system operations that manage the dynamic loading of classes, creation of external processes, and host environment inquiries.
The second unit describes the term introspection and its implementation with the Reflection class in Java. This unit also explains the classes and interfaces in the java.lang.reflect package. The methods of identifying the properties of objects at run time are discussed. The unit also explains the process to create objects for the class at run time.
In the third unit, you will learn about the classes that are available in the java.util.jar package. You will also learn to create a JAR file.
