I am trying to implement this with the help of enhanced for loop, but my question is if I use the iterator for the example below how do I make sure that my return type is picking up the corresponding value of "XYZ"?
List<Apples> a1 = new List<Apples>();
if(a1.iterator().next().equals("XYZ")
{
return a1.iterator().next().getFruits();
}
Probably you want to implement the following
List<Apples> apples = new List<Apples>();
for(Apple a : apples) {
if("xyz".equals(a.getSomethingWhatReturnsString())) return a.getFruits();
}
Why use an iterator here? a simple get()
will do the trick:
if (a1.get(0).equals("XYZ")) {
return a1.get(0).getFruits();
}
Of course, if you intend to traverse all the elements in a list then you're missing a for
here. And besides, your code won't work: it's a list of apples , you can't compare an apple with a string! Perhaps you meant something like this, replace getStringAttribute()
with the appropriate attribute that you intend to compare with "XYZ"
:
for (Apple a : a1) {
if ("XYZ".equals(a.getStringAttribute())) {
return a.getFruits();
}
}
