1 classic For
for (var i = 0; i < li.length; i++) {
// TO DO
var currentElement = li[i];
}
2 Enhanced For loop
for(final e in li){
//
var currentElement = e;
}
Notice the keyword final
. It means single-assignment, a final
variable's value cannot be changed.
3 while loop
var i = 0;
while(i < li.length){
var currentElement = li[i];
i++;
}
For the while
loop, you will use var
to reassign the variable value.
