HashMapis a very powerful data structure inJava. We use it everyday and almost in all applications. There are quite a few examples which I have written before onHow to Implement Threadsafe cache, How to convertHashmap to Arraylist? We used Hashmap in both above examples but those are pret...
A cache is an area of localmemorythat holds a copy of frequently accessed data that is otherwise expensive to get or compute. Examples of such data include a result of a query to a database, a disk file or a report. Lets look at creating and using a simplethread-safeJava in-memory c...
In this section, we’ll look at various ways to implement hash tables using JavaScript (and TypeScript). There are differences in languages like Java and Python (for example, in Java, you can use the HashMap interface as a part of the Java collection package). Still, ultimately, most gen...
This document describes what you need to do in order to integrate your provider into Java SE so that algorithms and other services can be found when Java Security API clients request them.
How to implement a global exception capture mechanism such as the ANR mechanism? How do I install a .hsp file to the device using the hdc command? How do I view stack traces for error logs generated in ArkCompiler? How do I view ArkTS parameters and switches of hdc? What are th...
log("==> Connected to Crunchify's Local Server Successfully."+" Host: localhost, Port: 11211"); // Set an object in the cache (using the default transcoder) regardless of any existing value. // The exp value is passed along to memcached exactly as given, and will be processed per th...

The JavaScript side uses bundleName to match abilityName of PAs on the Java side. After receiving a request from the JavaScript side, the system will handle the request in the invocation mode you have specified using the JavaScript API. You can implement the service logic provided by the PA ...
