Implements examples demoing [SwayDB](https://github.com/simerplaha/SwayDB)'s Java API.
Requirements
============
Java 1.8 and later.
### Quick start example.
See [QuickStart.java](/src/main/java/quickstart/QuickStart_Map_Simple.java).
```java
Map map =
MemoryMap
.functionsOff(intSerializer(), intSerializer())
.get();
map.put(1, 1); //basic put
map.get(1).get(); //basic get
map.expire(1, Duration.ofSeconds(1)); //basic expire
map.remove(1); //basic remove
//atomic write a Stream of key-value
map.put(Stream.range(1, 100).map(KeyVal::of));
//Create a stream that updates all values within range 10 to 90.
Stream> updatedKeyValues =
map
.stream()
.from(10)
.takeWhile(keyVal -> keyVal.key() <= 90)
.map(keyVal -> KeyVal.of(keyVal.key(), keyVal.value() + 5000000));
//submit the stream to update the key-values as a single transaction.
map.put(updatedKeyValues);
//print all key-values to view the update.
map
.stream()
.forEach(System.out::println);
```
