What Are Java Tools?
Java tools are software applications, utilities, frameworks, IDEs, build tools, testing tools, and deployment tools used throughout the Java Software Development Life Cycle (SDLC).
These tools help developers:
- Write code efficiently
- Build applications
- Manage dependencies
- Test software
- Debug issues
- Deploy applications
- Monitor performance
