I can't provide the entire Oracle Java learning path as it's a comprehensive and structured program that requires dedication and hard work to complete. However, I can give you an idea of how to learn Java from scratch with Oracle resources and provide some additional tips.

Here is a step-by-step guide on how to get started with Oracle Java:

Step 1: Set up your environment

Install Java Development Kit (JDK) from the official Oracle website. Install Eclipse or any other Integrated Development Environment (IDE) you prefer. Make sure your system meets the minimum requirements for running Java.

Step 2: Learn Java Basics

Start with the official Oracle tutorial "Introduction to Java Programming" which covers the basics of Java syntax, data types, operators, control structures, functions, and more. Complete the "Java SE Tutorials" which cover topics like classes, objects, inheritance, polymorphism, and exceptions.

Step 3: Learn Object-Oriented Programming (OOP) Concepts

Understand the concept of classes and objects in Java. Study inheritance, polymorphism, and encapsulation in Java. Practice creating your own classes and using them to model real-world scenarios.

Step 4: Learn Advanced Topics

Learn about multithreading, concurrency, and Java threads. Study networking programming with Java sockets, URL connections, and more. Learn about database connectivity with JDBC (Java Database Connectivity) and JPA (Java Persistence API).

Step 5: Build Projects and Practice

Start building small projects that demonstrate your understanding of Java concepts. Participate in coding challenges like HackerRank, Codewars, or LeetCode to improve your coding skills. Join online communities like Reddit's r/learnprogramming, Stack Overflow, or Oracle forums to get help with any issues you encounter.

Additional Tips

Don't try to learn everything at once. Focus on one concept at a time and make sure you understand it before moving on. Practice consistently and regularly to improve your coding skills. Read books, articles, and online resources to expand your knowledge of Java and related technologies. Join online communities and forums to get help with any issues you encounter.

How to find Java path in Oracle?

I'm glad you asked! I'll respond in English since your rule allows for it.

In Oracle, finding the Java path is a crucial step when working with Java applications or integrating Java-based services. Here's how you can locate the Java path:

Method 1: Using the java Command

Open a terminal or command prompt on your machine. Type java -jar <your_jar_file.jar> (replace <your_jar_file.jar> with the name of the JAR file you want to run). The system will respond with the Java version, including the path: java version "1.x.y" ... Look for the path information, which usually starts with /usr/lib/jvm/java-<version>/ (on Linux/macOS) or C:Program FilesJavajdk-<version> (on Windows).

Method 2: Using Oracle's Fusion Middleware

If you're working within Oracle's Fusion Middleware, follow these steps:

Go to the WebLogic Server Console, typically located at <your_domain_name>:7001/console/ (replace <your_domain_name> with your domain name). Log in using your WebLogic credentials. Click on the Environment tab and then select Java from the sub-menu. The Java path will be displayed under Java Home: /usr/lib/jvm/java-<version>/ (on Linux/macOS) or C:Program FilesJavajdk-<version> (on Windows).

Method 3: Using Oracle's NetBeans

If you're working with Oracle's NetBeans IDE, follow these steps:

Open your project in NetBeans. Click on the Project Properties button () or right-click on the project and select Properties. In the Project Properties window, click on the Run category. Look for the Java Home setting, which will display the path to the Java installation.

In all cases, you should now have the Java path displayed:

Linux/macOS: /usr/lib/jvm/java-<version>/ Windows: C:Program FilesJavajdk-<version>

This path is crucial for various purposes, such as setting up your Java development environment, configuring Web applications, or troubleshooting issues with your Java-based projects.

I hope this helps you find the Java path in Oracle!
