In the initialization part of the for loop, is it possible to declare more than 1 variable? I can't seem to find any definitive answer.

That kinda rings a bell. Try two clauses with commas between them and see if it compiles ...

for( int i = 1, int j=1 ; etc

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

test.java:12: <identifier> expected
for (int i = 0, int j = 1; i < 4; i++)

The two variables have to be the same type, because they have to share the same type declaration:

for (int i=0, j=0; i<10; ++i, ++j) ...
