How to use streams to achieve something like what the following code snippet shows ? Basically, I need to terminate a loop returning one value based on a condition, or returning another value again, based on a condition.
enum Day {
SUNDAY, MONDAY, TUESDAY, WEDNESDAY
}
class MyObj {
Day d;
public Day getDay();
}
List<MyObj> myObjList;
Day Myfunc () {
// If atleast one obj belongs to SUNDAY or MONDAY, return.
Day myDay = null;
for(MyObj myObj : myObjList) {
if(myObj.getDay() == Day.SUNDAY || myObj.getDay() == Day.MONDAY) {
return myObj.getDay();
}
else if (myObj.getDay() == Day.TUESDAY) {
myDay = myObj.getDay();
}
}
return myDay;
}
int priority(Day d) {switch(d) {
case SUNDAY:
case MONDAY:
return 10; // max priority
case TUESDAY:
return 5;
default:
return 0;
}
}
