What types of code does the translator handle?

The translator is optimized for interview and algorithmic code: sorting algorithms, binary search, graph traversal (BFS/DFS), dynamic programming, and common data structure operations. It handles variable declarations, loops, conditionals, functions, and print statements.

Q: Can I convert Python code to Java automatically?

Yes. Paste Python code in the left panel, select Java as the target language, and the translator converts loops, functions, data structures and print statements automatically. Best suited for algorithmic/interview-style code.

Q: Does this work for LeetCode solutions?

Yes, the translator is designed specifically for LeetCode-style algorithmic code. It handles common patterns like two pointers, sliding window, binary search, BFS/DFS, and DP table patterns across all four languages.

Convert algorithmic code between Python, JavaScript, Java, and C++ instantly. Designed for LeetCode solutions, interview prep, and common data structure patterns.

✅ What Gets Translated

Variables & types int x = 5 ↔ x = 5

Print statements System.out.println ↔ print()

For / while loops for(int i=0; ...) ↔ for i in range()

Functions / methods def foo(x): ↔ public int foo(int x)

If / elif / else elif ↔ else if

Arrays & lists [] ↔ ArrayList ↔ vector<>

HashMaps dict ↔ HashMap ↔ unordered_map

Return statements return x ↔ return x;

Comments # ↔ // ↔ /* */

String ops len(s) ↔ s.length() ↔ s.size()

Frequently Asked Questions

Can I convert Python code to Java automatically?+

Yes — paste Python code in the left panel, select Java as the target language, and click Translate. The tool handles variable declarations, loops, print statements, functions, and common data structures like lists and dicts.

Does this work for LeetCode solutions?+

Yes. The translator is built specifically for LeetCode-style algorithmic code — two pointers, binary search, BFS/DFS, DP tables, merge sort, and common string/array operations. Full programs with class definitions, imports, and complex generics require manual cleanup.

How do I convert Java to Python?+

Select Java as the source language and Python as the target. Paste your Java code and click Translate. The tool converts Java for loops, System.out.println, ArrayList, HashMap, and type declarations to equivalent Python syntax.

How accurate is the translation?+

The translator uses heuristic pattern matching optimized for algorithmic code. It handles ~85% of common interview patterns correctly. Edge cases: complex generics, lambda expressions, and OOP hierarchies need manual review. Always test the output.
