For- Loops and Printing

Posted: Nov 7, 2002 7:42 AM

I am working on arrays and everything works just fine except for my println statement. This println statement worked before I included the (names) line. I need to print all elements in both arrays together (as a list). Is it illegal to use two println statements for one for-loop?
Any input is appreciated!

}
for (int i = 9; i >= 0; i--)
System.out.println(names);
System.out.println(scores);
System.exit(0);

I used this loop: for (int i = 0; i<10; i++) {
earlier in my program and Java/Textpad gives me this error:
i is already defined in main(java.lang.String[])
for (int i = 9; i >= 0; i--)
^

I forgot to include the index:

you already declared int i in your first loop

try to delete int in the next loop, just initialize it.

Thanks! I figured it out. There was also something wrong with my inner for-loops.
