Code examples to demonstrate the new features from Java 10 and 11 release.
The LocalVariableTypeInference.java class have some code examples to demonstrate the Java 10 capability to infer the local variable type.
var list = new ArrayList<String>(); // infers ArrayList<String> var hashMap = new HashMap<String, String>(); // infers HashMap<String, String> var stringBuilder = new StringBuilder(); // infers StringBuilder()To ensure TypeInference from Java 10, the LocalVariableTypeInference.java class are fully reviewed by unit tests, that can be found in class HaversineAlgorithmTest.java.
@Test void localVariableTypeInferenceArrayList() { var optional = variableTypeInference.localVariableTypeInferenceArrayList(); var someObject = optional.isPresent() ? optional.get() : Optional.empty(); assertAll("localVariableTypeInference", () -> assertTrue(someObject instanceof ArrayList), () -> assertNotEquals(someObject, null) ); }Just open a terminal and paste the commands below:
