It should be replaced by < sign:
 for(int i = 0; i < fields.length; i++) {

If you replaced > with &lt; because you thought html would be rendered in your post, it was unnecissary.  I'm not sure if that was your question though.

If this was your question:
"What is the  purpose of  i<fields.length in this block of code?"
Then your answer is, i<fields.length is the condition that must be met before the loop will finish iterating.

A for loop consists of three parts, the initialization, the condition, and the statement.
for ( init   ;   condition   ;   statement )

The initialization sets an initial state for a variable.  The condition is the condition that the variable must be in before the loop will finish.  And the statement is what to do in order to change the variable in your condition.  For example,
for ( i=0; i<5; i++)
The first part "let there be a variable called i, and have it initially set to zero".  The second part says: "keep iterating through the loop while i<5 is true", and the third part says: "after each iteration through the loop body, increment i".

Sorry if that was confusing, I hope that helped.

"&lt;" is just HTML code for the character "<"  (lt stands for "less than")
"&gt;" is the HTML code for the character ">" (gt stands for "greater than")

I guess you get this by copying/pasting the code from the source code of an HTML page.
So, that should be:

          for (int i = 0; i < fields.length; i++) {
