Question

I have some code, like so:

int batchPosition = new Integer(batchBegin);

for (batchPosition;batchPosition<=batchEnd;batchPosition++)

But I get this error in eclipse:

Syntax error, insert "AssignmentOperator Expression" to complete ForInit.

I’ve looked at various posts on SO about this error, and googled it but I can’t figure out why this isn’t allowed.

batchPosition on it’s own is not a valid initialisation statement – you can simply skip it:

int batchPosition = new Integer(batchBegin);

for (; batchPosition <= batchEnd; batchPosition++)

But if you don’t need to access batchPosition after your loop, it is good practice to reduce variables scopes as much as possible:

for (int batchPosition = new Integer(batchBegin); batchPosition <= batchEnd; batchPosition++)
