Example

public class ClassA {

public void methodA ( List list ) {

for ( Iterator it = list.iterator(); it.hasNext(); ) {

int anInteger = 2;
Object obj = it.next();

// do something with obj and anInteger...
}
}


Solution
Avoid declaring or assigning variables inside a loop that are not dependent on the loop condition.
Where possible, assign them outside the loop to avoid incurring extra costs.

public class ClassA {

public void methodA ( List list ) {

int anInteger = 2;
Object obj;
for ( Iterator it = list.iterator(); it.hasNext(); ) {

obj = it.next();

// do something with obj and anInteger...
}
}
