JDK 1.1 Packages
| java.applet
java.awt java.awt.datatransfer java.awt.event java.awt.image java.awt.peer java.beans java.io |
java.lang |
java.security |
| Improvements: | - JAR files allow all the grouping of of an applet's
files into a single archive - Digital signatures allow trusted applets to run with fewer security restrictions |
| Java 1.1 AWT included support for printing, cut-and-paste,
popup menus, menu shortcuts, and focus traversal as well It has also improved support for colors, fonts, cursors, layout management, scrolling, image manipulation, and clipping |
| The classes and interfaces in this package define a
generic framework for inter-application (and intra-application) data
transfer Uses a DataFlavor object to represent the type of data to be transferred Also includes classes to support a clipboard-based cut-and-paste data transfer model. This works for Java applications running on separate VMs too, or even for other, non-Java applications that run under the OS itself One of the two underlying data transfer mechanisms supported by this package relies on the Object Serialization API of the java.io package |
| A package for handling numbers with arbitrary precision The BigDecimal class gives its user complete control over rounding behavior, forcing the user to explicitly specify a rounding behavior for operations capable of discarding precision Eight rounding modes are provided for this purpose - BigDecimal - BigInteger |
| A package for handling Zip-files To list the files in a Zip-file:
ZipFile zipf = new ZipFile(filename);
for (Enumeration e = zipf.entries() ; e.hasMoreElements() ;) {
ZipEntry entry = (ZipEntry)e.nextElement();
System.out.println(entry.getName() + ": " +
entry.getSize()/1024 + " KB");
}
|
| A package for handling international and country specific
information It contains classes with information about: - DecimalFormats - DateFormats - MessageFormats - Locale-specific text splitting |
| Java Database Connectivity A class for interfacing databases through an SQL interface JDK contains a Bridge-interface to Microsofts ODBC Database manufacturers must provide their own implementation and must conform to the standard API |

- Cryptography |
