Java Programming with J2SE 5: Java Utilities

Course details

To enable the learner to use the classes and methods of the java.lang, java.util, java.io, and java.nio packages

• The Java Math class
• use the methods of the Java Math class to determine the value of a variable in a given piece of code, and associate the new methods of the Math class with their corresponding functions.
• Java wrapper classes
• use the utility methods of the Java wrapper classes to compare wrapper objects, transform values into strings, and extract values from wrapper objects.
• Managing Java wrapper types
• use the new methods of the Integer and Long wrapper classes to manipulate bits for a given scenario, and specify the code required to perform automatic conversions between primitive and wrapper types in J2SE 5.0.
• Java String, StringBuffer, and StringBuilder classes
• specify the code required to test the equality of strings, carry out pattern matching in regular expressions, and modify strings and string buffers for a given scenario.
• Manipulating Java strings
• use the Java String class to manipulate strings and define regular expressions.
• Java system operations
• specify the code required to modify system resources for a given scenario.
• Interacting with the system
• specify the code required to access, modify, and launch system properties, and create operating system processes for a given scenario.
• Using system operations
• access and edit system environmental variables, launch system processes, and retrieve system timing information.
• Collection Framework interfaces
• manipulate and traverse the elements of a collection for a given scenario.
• Using the Collection Framework in Java
• use Java's Collection class to modify, sort, and search a collection in a given scenario.
• Working with collection classes
• use iterators to traverse the elements of a list in a given code sample, and sort and modify the list elements using the Collections class.
• Using Collection classes
• select the appropriate Collection classes, interfaces, and method implementation to meet the requirements of a given scenario.
