In modern application architecture and development, there has been a push from monolithic applications towards microservices. This has made microservices frameworks (micro-frameworks) very popular since they make it easier to prototype, design and build microservices applications. Spring Boot and Quarkus are both very popular microservices frameworks for building cloud native Java applications.
An exception is an unwanted or unexpected event that occurs during the execution of a program which changes its normal flow. Exception handling is the mechanism to respond to and investigate the occurrence and cause of an exception. Generally, exceptions are of two types - checked and unchecked.
Memory management is Java’s strongest suit and one of the many reasons developers choose Java over other platforms and programming languages. On paper, you create objects, and Java deploys its garbage collector to allocate and free up memory. But that’s not to say Java is flawless. As a matter of fact, memory leaks happen and they happen a lot in Java applications. We put together this guide to arm you with the know-how to detect, avoid and fix memory leaks in Java.
The Java Persistence API (JPA) is used in most Java applications to interact with a relational database. One of its most popular implementations is the Hibernate ORM, because it uses object-relational mapping to abstract database interactions and makes implementing simple CRUD operations very simple. But this abstraction also has its downsides. Hibernate uses a lot of internal optimizations and hides all database interactions behind its API.
Have you ever wondered, while manually creating tests in Loadero, that it would be nice to have some library that you can use to create tests programmatically? Sounds nice, isn’t it? Well, luckily, Loadero does have this option now. In this blog post I would like to introduce you to the recent creation of Loadero’s team — Loadero Java library.
The java.lang.NullPointerException is a runtime exception in Java that occurs when a variable is accessed which is not pointing to any object and refers to nothing or null. Since the NullPointerException is a runtime exception, it doesn't need to be caught and handled explicitly in application code.
At Snowflake Summit 2021, we announced that Snowpark and Java functions were starting to roll out to customers. Today we’re happy to announce that these features are available in preview to all customers on AWS today. These features represent a major new foray into data programmability, enabling you to more easily make Snowflake’s platform do more for you. Snowflake started its journey to the Data Cloud by completely rethinking the world of data warehousing to accommodate big data.
In this post, we will discuss some of the primary commands, tools, and techniques that could help to monitor CPU Memory and Disk Usage in Java. The Java tools observe Java bytecode constructs and processes. Java Profilers follow all system commands and processor usage. This lets you look at call arrangement at whatever point you prefer.
Java memory analysis is an important process in checking the performance of a Java application. It helps Java developers ensure the stability of the application by checking the memory consumption. There are several factors to look into when doing memory analysis. But to get to the bottom of this process, it is vital to learn first how memory works.
