In Jasmin, only simple decimal and integer numeric formats are recognized. Floats in scientific or exponent format are not yet supported. Character codes and octal aren't currently supported either. This means you can have:
1, 123, .25, 0.03, 0xA
but not
1e-10, 'a', '\u123'
So on the last problem of the homework you will have to manually translate character constants to their 32 bit ASCII code.
java -jar
Execute a program encapsulated in a JAR file. The first argument is the name of a JAR file instead of a startup class name. In order for this option to work, the manifest of the JAR file must contain a line of the form Main-Class: classname. Here, classname identifies the class having the public static void main(String[] args) method that serves as your application's starting point. See the Jar tool reference page and the Jar trail of the Java Tutorial for information about working with Jar files and Jar-file manifests.
When you use this option, the JAR file is
the source of all user classes, and other user class path settings are ignored.
Note that JAR files that can be run with the "java -jar" option can have their execute permissions set so they can be run without using "java -jar". Refer to Java Archive (JAR) Files.
So try appending the following line to your classpath:
C:\Program Files\jasmin-2.3\build\jasmin\classes
Note that this directory contains Jasmin.class, which appears to be in the default package.
