if( masterList[z].list2 != NULL && masterList[z].list2.length() > 0 )
{
for( Integer y = 0; y < masterList[z].list2.length(); y++ )
The if-statement is a good summary of what is wrong with Java. The author doesn't even notice that the second argument of && is redundant and keeps it in the "refactored" version as well...
