A Java representation of the SQL TIMESTAMP type. It provides the capability of representing the SQL . HashMap (java.util) HashMap is an implementation of Map. All optional operations are supported.All elements are permitte. List (java.util) A List is a collection which maintains an ordering for its elements.

GetOrElse. Here is another method on an Option. We can use getOrElse to access the inner value of the Option, unless there is None. If None, we get the argument back. So: We provide a default value. This helps us handle cases where None can occur.

A map cannot contain duplicate keys; each key can map to at most one value. This interface takes the place of the Dictionary class, which was a totally abstract class rather than an interface.. The Map interface provides three collection views, which allow a map's contents to be viewed as a set of keys, collection of values, or set of key-value mappings.

GetOrElse. Here is another method on an Option. We can use getOrElse to access the inner value of the Option, unless there is None. If None, we get the argument back. So: We provide a default value. This helps us handle cases where None can occur.

getOrElse (T value1, T value2) Mimic of Oracle's nvl() - returns the first value if not null, otherwise the second value. Methods inherited from class java.lang.Object

Converting to Java #. If you need to convert an Option type to a null-able Java type for interoperability HashMap[java.lang.Long,java.lang.Long]() map: scala.collection.mutable. HashMap[Long,Long] = Map() scala> val b = map.getOrElse(1,0L) b: Any = 0 Returns an element at the given index or the result of calling the defaultValue function if the index is out of bounds of this array.

If a value is present, isPresent() will return true and get() will return the value. Additional methods that depend on the presence or absence of a contained value are provided, such as orElse() (return a default value if value not present) and ifPresent() (execute a block of code if the value is present).
