Write the following code at two blocks between start and end comment.

The following code is for you to copy and paste:

@Test void should_be_able_to_bind_to_instance_method() { // TODO: // please bind lambda to `instanceMethod()` in this class. //  assertEquals("instanceMethod", lambda.getString()); } @Test void should_be_able_to_bind_to_static_method() { // TODO: // please bind lambda to `staticMethod()` in this class. //  assertEquals("staticMethod", lambda.getString()); } private static String staticMethod() { return "staticMethod"; } private String instanceMethod() { return "instanceMethod"; }

@Test void should be able_to_bind_to_instance_method() { // TODO: // please bind Lambda to 'instanceMethod()' in this class. // assertEquals( expected: "instanceMethod", lambda.getString()); } @Test void should be able_to_bind_to_static method() { // TODO: // please bind Lambda to 'staticMethod()' in this class. // assertEquals( expected: "staticMethod", Lambda.getString()); } private static String staticMethod() { return "staticMethod"; } private String instanceMethod() { return "instanceMethod"; }
