JDK (Java Development Kit) on HKUSUA system
We are pleased to announce the availability of the JDK (Java Developers Kit)
release 1.0.2 on the HKUSUA system. This JDK contains the necessary tools for
developing Java applications and Java applets that conform to the Java applet
API 1.0 (provided with the JDK).
Both Java applications and Java applets are written in the Java Programming
Language. A Java application is a complete program which is developed for
standalone running, e.g. the Java- enabled browser. A Java applet is quite
similar to a Java application except that an applet has to be run within a
Java-enabled browser, like the Netscape V2.0 on Sun Solistic 2.4 and Windows
The JDK consists of the following components:
javac: the Java Language Compiler for compiling programs written in Java
Programming Language into bytecodes.
java: the Java Language Runtime for running programs written in Java
jdb: the Java Language Debugger for finding and fixing bugs in Java programs.
javah: C header files and C stub files for a Java class; these files would
allow your code written in Java Programming Language to interact with
the program codes written in other languages like C.
javap: for disassembling compiled Java files.
javadoc: for generating API documentation in HTML format from Java source code.
appletviewer: for running applets without a using World-Wide Web browser.
To compile a Java program, its source program must be contained in a file with
".java" as the filename extension. For each class defined in the source
files which are passed to Java compiler, javac, it will store the resulting
bytecodes in a file named classname.class. By default, all the resulting
To compile a Java source program into Java bytecodes, invoke the command
"javac" at the system prompt of HKUSUA, as follows
When the compilation is successful, the command "java" can then be issued at
the system prompt of HKUSUA to invoke the Java interpreter to translate and
execute the bytecodes, as follows:

FORTRAN 90 Compiler on HKURSC
The FORTRAN compiler on HKURSC system has recently been upgraded to version
This upgraded version of FORTRAN compiler which can be invoked by the "xlf"
command is capable of compiling FORTRAN programs written in either FORTRAN 77
or FORTRAN 90 programming language.
In addition to FORTRAN 77 compatibility, the FORTRAN 90 programming language
provides a few new functions to facilitate development of scientific and
engineering programs. Such new features include Array operations, Structured
programming constructs, non-advancing input/output and recursive procedures.
The following example shows the comparison between the use of FORTRAN 90 array
operation for adding two arrays and the use of FORTRAN 77 language for the
FORTRAN 90 coding :
Real, dimension (5,6):::A,B,C
FORTRAN 77 coding :
Do 100 i=1,5
Do 120 j=1,6

Reduction in Maintenance Charge for Microcomputer Systems
Computer Centre is pleased to announce that there will be a reduction in
maintenance charge with effect from July 1, 1996 on microcomputers and their
peripherals which are supported by the in-house Maintenance Team of the
Computer Centre . The models of microcomputers that will benefit from this
price reduction include 486PC, Macintosh and especially on Pentium. The aim
of Computer Centre's in-house maintenance service is to provide cost
effective and efficient hardware maintenance support to the large and ever
growing population of microcomputer equipment of the University. The
reduction in maintenance charge is possible because there has been price
reduction for some spare parts, especially the CPU board, hard disks and
memory boards and more users are joining the maintenance. We believe that the
price is very attractive to all users and departments. If you are interested
in joining this service, please contact Miss Heti Cheng at 2859 2491.
The new maintenance charges of the common microcomputer systems are summarized

UIS Annual Leave System Course for Departmental Leave Administrators
Computer Centre has developed a software system for the management of
annual leave application and records for staff in the University. It will
automatically generate a year-end summary report of the annual leave balance
of the staff of a department according to the requirement of the Registry. An
up-to-date leave balance for all staff is also maintained by the system.
The Annual Leave System is evolved as an application under the UIS. It
provides the facilities for staff to apply and cancel leave, and for the
department head or his delegated authority to approve and reject leave
applications through networked PCs. Staff in a department can check through
the system the leave of absence of other colleagues in the same department.
In order to make use of the system, a department head must nominate one or
more staff in his department to act as the Annual Leave Administrator who will
be who will be in charge of the system, e.g. to register the initial leave
balance of a new staff with the Annual Leave System. Nominations of annual
leave administrators should be made by filling in the "UIS application form -
department head proxy application" and return it to Computer Centre .
Two workshops, namely the Beginner Course and Refresher Course, for Annual
leave Administrators of departments will be conducted in the summer to provide
training for the leave administrators.
Course No : C0112796 - Beginner Course for UIS Departmental Leave Administrators
Departments which are new to the system or have missed the training course
last year should attend this course. The course will cover all functions
offered by the system with hands-on training.
Course No : C0112797 - Refresher Course for UIS Departmental Leave
Departments which are already using the system are invited to attend the
refresher course. The course will not go into the fine details of using the
system as the administrators should be familiar with the day to day running
of the system. Instead, the course will give a brief overview of the system,
followed with a question-and-answer session for the queries that
administrators might have in using the system.
Course No. Title Date/Time Venue
C0113296 Beginner Course for UIS July 17, 1996 Old Library Building
Departmental Leave 2:300 pm-5:30 pm first floor, LBO-135
C0113396 Refresher Course for UIS July 18, 1996 Old Library Building
