Can I use adb to change the default launcher program?

Question

I set one of the program as default launcher program and default setting program so I cannot change the default programs now, can I change the default programs from android-sdk\android-sdk\platform-tools\adb.exe or remote shell.

How can I do that?

And can I remove the defaults of program in Java code?
