<DD>

Any command that returns a Java object or primitive Java type will
automatically convert the object or primitive type to a corresponding
Tcl value. This conversion can be skipped by using the <B>-noconvert</B>
option. This applies to the <b>java::call</b>, <b>java::field</b>,
<b>java::prop</b>, <b>javaObj</b>, and <b>javaArrayObj</b> commands. The
<b>java::new</b> command does not do any conversion because it
makes no sense to convert a Java object that was just allocated.
If the returned value is a primitive Java type it will be converted
to an integer or floating-point Tcl value. If the result is a <b>String</b> object,
then the Java string object is converted into a Tcl string. For all other
object types, a Java object handle is created and returned. If the
<B>-noconvert</B> option is specified a Java object handle is always returned.


<P>

Tcl values are also be converted to Java objects and primitive Java types
when they are given as arguments to Java commands. The default conversion
for all Tcl values is a <b>java.lang.String</b> object. To override this default a
full signature must be provided for Java method invocations.
