java-magic 0.1.3

Magic cell para ejecutar Java de forma interactiva en Jupyter y Colab

Jupyter Java Magic (with Interactive Mode) A lightweight Jupyter Notebook extension to write, compile, and execute Java code directly inside cells. It features automatic Google Colab setup and real-time interactive console input support (Scanner, System.in).

🛠️ Installation

pip install java-magic

🚀 Quick Start

1. Load the extension In your first notebook cell, load the magic:

%load_ext java_magic

2. Run standard Java code You don't even need a main class wrapper for simple snippets; the extension handles it automatically:

%%java
System.out.println("Hello from Jupyter!");

3. Run interactive Java code If the extension detects Scanner or System.in, it automatically switches to an interactive terminal loop:

%%java
import java.util.Scanner;

Scanner scanner = new Scanner(System.in);
System.out.print("Enter your name: ");
String name = scanner.nextLine();
System.out.println("Hello, " + name + "!");

⚙️ Configuration By default, generated .java files are kept in your directory. If you want them automatically deleted after execution, run:

%config JavaMagics.remove_java_file = True
