There are currently no universal tools that can convert Java code to Python code automatically with 100% accuracy. The syntax, structure, and language characteristics of Java and Python are fundamentally different. Here are few reasons why:

1. Static vs Dynamic Typing: Java is a statically typed language where each variable must be declared with a predefined data type, while Python is a dynamically typed language that determines the type of data at runtime.

2. Object Orientation: Both are object-oriented languages, but they have different approaches. In Java, everything is an Object. In Python, object orientation is optional and we can create procedural code.

3. Syntax: Java syntax is quite different from Python. Python syntax is meant to be more readable and simpler, while Java syntax is more complex.

4. Memory Management: Java has built-in garbage collection, whereas Python has both reference counting and a cycle-detecting garbage collector.

5. Error Handling: Exception handling is mandatory in Java, while it’s optional in Python.

So, direct conversion would be very tricky and potentially inaccurate.

However, to help you convert the code, the best approach would be to understand the logic in the Java code and rewrite it in Python.

Here is a simple example:

Java code:

Python equivalent:

For more complex tasks, you would have to convert the logic step by step, consider the different data types and structures each language uses, and adjust accordingly.
