aws lambda core

Learn how to create AWS LAMBDA functions This execute on a scheduled interval and much like a cron job would. In this lesson we'll create a LAMBDA function that checks for a string of text on a website to verify the website are up and operational. The lambda function logs to CloudWatch Metrics and sends a notification

references cannot exist independently and are always converted to instances of a functional interfaceYou can use this and the super parameter in a method referenceThis::equals equivalent to X->this,equals (x)3.5 constructor ReferenceA constructor reference is similar to a method reference, except that the method name is new. For example, Person::new is a reference to the person constructor. Which constructor is called depends on the context.You can establish a constructor reference with an arra

Lambda An expressionform: parameter, arrow (-), expressionParameter type to write, if you can deduce it can not writeOnly one argument can omit parenthesesNo arguments to write empty brackets ()* If the branch returns a value, then all branches will return a value, otherwise it is illegalfunction interface: interface with only one abstract method (can be marked with @functionalinterface annotations)For example, you can do this in Javax.swing.Timer.

Compare (salary, other.salary); 5 }}Note the type conversion of the Object parameterWhy not provide a Comparableto method directly in the employee class? The main reason is that Java is a strongly typed (strongly typed) language.

1. Interfaces are key object-oriented features: They let you specify what should be done without providing the implementationRecently, the importance of functional programming for concurrency and event-driven programming has improvedAll methods of the interface default to the public method, without the need to explicitly declare theThe implementation class must declare the interface methods public, otherwise they will be accessible at the package level by default. The interface requires the publ
