CLDC defines the following requirements:

• Full Java language support (except for floating pointer support, finalization, and error handling)
• Full JVM support
• Security for CLDC
• Limited internationalization support
• Inherited classes -- all classes not specific to CLDC must be subsets of J2SE 1.3 classes
• Classes specific to CLDC are in javax.microedition package and subpackages

In addition to the javax.microedition package, the CLDC API consists of subsets of the J2SE java.io, java.lang, and java.util packages. We will cover details in the section on CLDC API and will use the CLDC API to develop our drawing application.
