Java is a computer language that needs no introduction in the field of software development. Although a little over three decades old, Java has remained relevant by continually providing value year after year and changing with the times. Despite the fact that we have entered an era of microservices and distributed software architectures, Java remains the most popular programming language for it.

In this blog will explain What are the Advanced Java Debugging Techniques.
Why Choose Advanced Java For Software Development?
- Client-server decoupling improves the end-user experience because the front-end look and feel are unrelated to the back-end functionality.
- Advanced Java has a streamlined component-based architecture. Simultaneously, it has the ability to give rise to complex, multi-tier applications.
- Configuring application behaviour during application assembly or deployment lowers the need for recoding.
- The architecture is straightforward yet modular, allowing for rapid development, deployment, and maintenance.
- Several APIs, including JDBC, JTA, JNDI, JMS, JavaMail, and others, help to broaden the scope by interacting with a wide range of current information systems and databases.
5 Advanced Java Techniques of Debugging
Once you’ve mastered the notion of debugging using the first three stages of the four-step cycle outlined in the preceding section, it’s all about implementing techniques to address the problems. The different specialised Advance Java debugging techniques that will be used can be broadly characterised as follows:
Use Breakpoints
A breakpoint is a line of code that is intentionally included with the goal of stopping or pausing programme execution at that exact moment. The breakpoint invokes the debugger or causes a CPU interruption during programme execution. As a result, the programme enters extraordinary handling mode.

Print Debugging
Have you ever come across an error that causes the application to dump garbage values across the screen while it performs debugging? Then you already have a slight idea of what print debugging entails. This widely used Advanced Java debugging technique prints random values during application runtime and displays them at the console or user interface. It is often used by developers to comprehend the flow within the function or service and the logic or data transfer taking place in the background. The print statements are based on pure assumptions (rather than resting on logic) and are incorporated within the code depending on the developer’s judgment of where the bug resides.
Remote Debugging
This Advanced Java debugging technique, as the name implies, takes place remotely, with the debugger and the programme not colocated on the same server or platform. Because of their complementary nature, Advanced Java debugging tools are frequently used in tandem with production debugging.
When we design a software programme for a single or a small number of devices, we use the fewest resources possible. As a result of this limitation, the code for executing the application and the code for debugging cannot coexist. This is when remote debugging comes into play.
Memory-Dump Debugging
A memory dump is a snapshot of memory and associated data taken when an application crashes. Consider it a black box within an aeroplane. The’stack trace’ from this memory dump can be extracted by developers to determine when, when, what, and how the programme failed. The stack trace would include a log of the individual functions, global and local variable values, and other crucial data at the time of the crash. Then it’s all about reverse-engineering the results and tracing the causes that led to them.
Replay Debugging
The Advanced Java Replay Debugging principles necessitate that developers capture the complete programme execution process. They will replicate all data exchanges, events, memory management, data updates, user inputs, and output displays that would ordinarily occur throughout the usual course of events during this step.
