Looping through a Map
I want to do similar thing below , but using a Map, is there any similar funcationality available?
The list or set iteration for loop iterates over all the elements in a list or set. Its syntax is:
for (variable : list_or_set) {
code_block
}
where variable must be of the same primitive or sObject type as list_or_set. When executing this type of for loop, the Apex runtime engine assigns variable to each element in list_or_set, and runs the code_block for each value. For example, the following code outputs the numbers 1 - 10 to the debug log:
Integer[] myInts = new Integer[]{1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
for (Integer i : myInts) {
System.debug('test test');
}
I tried this but got error,
public Map<Integer, myClass> myItems;
for (myClass item : this.myItems){}
Save error: Loop must iterate over a collection type: MAP<Integer,myClass> :(
Can anyone help on this?
Thanks
for(integer varI : myItems.keyset())
{
variable=myItems.get(varl);
Logic....
}
OR
for (myClass item : myItems.values()){}
please mark as accepted if its your solution

for (myClass item : myItems.values()){} works :-)
