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]


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.


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?

Basic Variable Types in Python

This written lesson is part of Banana Chip Tech’s Python Crash Course. For video lectures, programming homework assignments, and other content please visit our website.

Variables are ways that we can store information for use later on in a program. For this reason, they are incredibly helpful when programming. The way that I like to think about variables are like jars where we can stuff information in and then take information out later. A good real world example of what a variable does can be found in food containers. The food container itself would be the variable and the food that it holds would be the data that a variable would hold. For instance, we can store some peanut butter in our peanut butter jar. We can then take our peanut butter out of the jar and use it when we want to make our peanut butter and jelly sandwich. Similarly, we can have a pizza box which is holding our pizza. Later on when we are hungry, we can take out a piece of pizza and eat it. Both the peanut butter jar and pizza box act as storage containers, but _what _they store is different. All python variables store information, but the type of information that they store differs.

While python doesn’t force you to document what specific type of variable you’re going to be using, knowing the type of variable used can be critical for the success of your program. I like to classify python variables into two distinct types: basic variable types and data structure variable types. In this tutorial, we talk about the different basic variable types.

Basic variable types contain only a single piece of information. These basic variable types are like our peanut butter jar that only stores peanut butter. We can’t store cheese or bread in our peanut butter jar; we can only store peanut butter!

The first basic variable type that we will discuss is the integer (int). Ints are whole numbers that don’t have a decimal. They can be positive or negative as long as they don’t have a decimal. The following code provides a demonstration of creating an int. Notice that the equal sign is used to assign the value 3 to the variable named myint. For simplicity sake, I recommend using only letters and underscores in your variable names. Avoid using any keywords (ie: for, in, while, if, etc) in your variable names. Following these recommendations will help you avoid any invalid variable names!
