Installing J/Link

J/Link Mathmatica package is loaded.

InstallJava[ ] setups J/Link environment so that the Mathmatica can use Java. Options of InstallJava[ ] varies depending on which machine and operating system a user is using.

JavaBeans  Object

Definition of a JavaBeans is stored in MrBeans.jar in the system. The TinyBean has one property "count" as int.

By default the value of the count is 100.

The value is changed to 200.

Loading Serialized Object In The File

The serialized object of the JavaBeans is stored in tiny.ser file, where the value of the count property has been set to 4321.

The serialized object in the file is deserialized.

Saving JavaBeans Into The File

The obj which has new value is serialized into a new file.

Checking New Beans

We can easily check the value of new beans stored in the new file by loading it again.

Removing J/Link
