Why Python Soars and Java Slides: Insights from the 2025 TIOBE Rankings

Ranking Analysis

According to the TIOBE June 2025 ranking, the top ten programming languages are:

1. Python – 25.87% (+10.48%)

2. C++ – 10.68% (+0.65%)

3. C – 9.47% (+0.24%)

4. Java – 8.84% (+0.44%)

5. C# – 4.69% (-1.96%)

6. JavaScript – 3.21% (-0.11%)

7. Go – 2.28% (+0.35%)

8. Visual Basic – 2.20% (+0.54%)

9. Delphi/Object Pascal – 2.15% (+0.62%)

10. Fortran – 1.86% (+0.33%)

Why is Python soaring again?

Python remains the champion, gaining nearly 10.5% and accounting for about 26% of the share, roughly equal to the combined share of C++, C, and Java. Its explosive growth is driven by the AI boom, as Python is the de‑facto language for machine learning, deep learning, and large‑language‑model development.

However, entering AI development requires mastery of the full AI toolchain (NumPy, Pandas, TensorFlow) and strong mathematical and logical reasoning, often demanding graduate‑level education and intensive benchmarking.

Why do C++ and C stay in the top three?

C++ and C retain high rankings because they are indispensable for game development, graphics, embedded systems, browser engines, and high‑frequency trading. Modern C++20 introduced extensive syntactic sugar and concurrency models, making the language more expressive while preserving its performance and reliability.

C remains essential for low‑level drivers, firmware, and control systems in smartphones, routers, and medical devices, especially as IoT expands.

Why has Java dropped to fourth?

Java’s decline is not due to weakness but to the rapid rise of the languages ahead. Its share grew modestly by 0.44%, keeping it at fourth place. Java still offers stability, a rich ecosystem, and strong enterprise adoption, with recent features like lambdas, virtual threads, and pattern matching, as well as Spring AI integration for AI workloads.
