Dynamically set local variable [duplicate]

Contrary to other answers already posted you cannot modify locals() directly and expect it to work.

lcl = locals()
lcl['xyz'] = 42

Batch file to delete files older than N days
...
My thoughts were more along the lines: "My files are already where I want them. I don't want to have to move them." "Deleting files is logically what you're doing, so do that. Don't overload Robocopy to do it"

Note that it is a good style to always put the newline as a last character if it is allowed by the file format. Furthermore, for example, for C and C++ header files it is required by the langua...
Passing a Bundle on startActivity()?
...mIntent.putExtra(key, value);
Then, in the launched Activity, you would read them via:
String value = getIntent().getExtras().getString(key)
NOTE: Bundles have "get" and "put" methods for all the primitive types, Parcelables, and Serializables. I just used Strings for demonstrational purposes....
Does Java support default parameter values?
