convertReverse

convertReverse( String javaCode ) → String

The goal is to take Java snippets and turn them into Jython code. This is all overly simplistic and should be done properly. Cheesy! More TODOs: throw IllegalArgumentException -> raise exception Character.isDigit -> string.isnumeric "".startsWith -> "".startswith "".trim() -> "".strip() || -> or && -> and ! -> not int[] d -> d System.arraycopy -> for i in range(0,6): a[i]=a[i+6]

Parameters

javaCode - a String

Returns:

conversion to Jython-like code.
