For the most part, it "Just Works". Essentially, for wrapping Java
objects in Objective-C (which is the only direction with which I am
familiar), you can simply use the Objective-C syntax to call methods on
the Java objects, and most type coerecions are handled for you
automatically.
You can get a Class object representing a Java object using
NSClassFromString():
For example:
NSClassFromString(@"java.util.Vector")
You can then treat the result as if it were an Objective-C class:
id theJavaVector = [[NSClassFromString(@"java.util.Vector") alloc]
init];
[theJavaVector addElement: @"A string"];
[theJavaVector addElement: @"Another string"];
[theJavaVector addElement: [NSNumber numberWithInt: 42]];
