Can anyone do python to java conversions?

[nevets04]

I dont understand what those methods/functions in Python do. I can however convert them if i know their task. What do these do;

Code:

chr()

len()

ord()

list()

And I know the append() method. Are you trying to append text through a GUI or just through the use of writing to something?

Just through the use of writing something.
I also find len() it is String.length()
as for chr and ord
chr(97)
outputs a. I believe its hex
and ord('a') outputs 97, Its the opposite of chr
