Cant compile this simple line!

This line wont compile for some reason:

String tempString = theFile[z].toString ().replace (tempChar, key[v][[100 * (int) Math.random()]);

C:\Program\Java\jdk1.6.0_23\jre\classes\pjjava\crypt\cryptMethods.java:170: illegal start of expression
				String tempString = theFile[z].toString ().replace (tempChar, key[v][[100 * (int) Math.random()]);
				                                                                     ^

Why have you got two '[' next to each other?
