I have a class structure like this:
public class Foo {
private FooB foob;
public Optional<FooB> getFoob() {
return Optional.ofNullable(foob);
}
}
public class FooB {
private int valA;
public int getValA() {
return valA;
}
}
My objective is to call the get method for fooB
and then check to see if it's present. If it is present then return the valA
property, if it doesn't then just return null. So something like this:
Integer valA = foo.getFoob().ifPresent(getValA()).orElse(null);
Of course this isn't proper Java 8 optional syntax but that's my "psuedo code". Is there any way to achieve this in Java 8 with 1 line?
