How Can I See Variable Values When Debugging?

One of the primary tasks you’ll want to perform when using the debugger is determining the value of different variables. Visual Studio has various windows which can reveal this information, and allow you to dig into the specific ones you’re seeking. Leslie Richardson (@lyrichardson01), PM on the Visual Studio team, will show us some of her favorite ways to navigate variables in the debugger.

Did you know… You can find out all about the debugger on Microsoft Docs!

Reference Variable in Java

Before We Started with the Reference variable we should know about the following facts.

**1. **When we create an object(instance) of class then space is reserved in heap memory. Let’s understand with the help of an example.

Demo D1 = new Demo();

Reference Variable

Now, The space in the heap Memory is created but the question is how to access that space?.

Then, We create a Pointing element or simply called Reference variable which simply points out the Object(the created space in a Heap Memory).

Heap Memory

**Understanding Reference variable **

1. Reference variable is used to point object/values.

**2. **Classes, interfaces, arrays, enumerations, and, annotations are reference types in Java. Reference variables hold the objects/values of reference types in Java.

3. Reference variable can also store null value. By default, if no object is passed to a reference variable then it will store a null value.

**4. **You can access object members using a reference variable using **dot **syntax.

Scope of a Variable In Java [With Coding Example]

Introduction

Programmers define the scope of a Variable in Java that tells the compiler about the region from where a variable is accessible or visible. The scope of a variable in Java is static by nature. It means we have to declare it at compile time only. In this article, you will learn about the scope of a Java variable along with its types

What Is the Best Java Debugger?

Many people might think this a simple question; I am not one of them. I feel that in the modern world of development, there are too many factors to pick a single tool for debugging any language, let alone Java.

In The Beginning

Let’s take a step back and look at where we started with debugging, and while I am not going to get into the history of debugging, we should look at some of the basic tools used for debugging Java, aside from logging and system-out.

JDP

Let’s start with a quick look at the Java debugger (Java Discovery Protocol - JDP), which is a command-line tool used for debugging Java applications. This tool ships directly from Oracle, so you can be sure it will work; however, it can be complex to use and require knowledge of where you want to debug ahead of time.

A positive aspect of this tool is the fact that you can use it on the same box where the Java Virtual Machine (JVM) is running. This set-up means you do not need to deal with the complexities of connecting any external service that might be restricted by firewalls, which is particularly useful if you are deploying your Java applications into Docker containers. (which let’s be honest, who isn’t).

And while a command-line tool is not the best option for everyday work, what other options are available?
