How to Get the Current Working Directory in Java? 📂

Have you ever encountered a situation where you needed to access the current working directory in your Java code? Whether you want to manipulate files, navigate directories, or simply print the current path for debugging purposes, knowing how to obtain the current directory is essential. In this blog post, we will address common issues related to this question and provide you with easy solutions. Let's dive in! 💻

The Problem: 🚫

Before we jump into the solutions, let's take a look at the output and understand why it might not be what we expected:

Current dir: C:\WINDOWS\system32
Current dir using System: C:\WINDOWS\system32

If you expected to see your project directory or the directory where your Java code resides, this output might have left you scratching your head. The reason for this discrepancy lies in how the working directory is determined by default.

Solution 1: java.io.File 👍

In order to obtain the actual working directory, you can use the java.io.File class in the following way:

String currentPath = new java.io.File(".").getCanonicalPath();
System.out.println("Current dir: " + currentPath);

This code snippet will print the current working directory correctly. However, there is an even simpler solution that you can use.

Solution 2: System.getProperty 👌

Java provides a system property called "user.dir" that holds the value of the current working directory. By utilizing this property, we can obtain the current directory with just a single line of code:

String currentDir = System.getProperty("user.dir");
System.out.println("Current dir using System: " + currentDir);

By executing this code snippet, you will get the actual current working directory. 🎉
