- It has huge community support (tens of millions of developers)
- Java works on various platforms (Windows, Mac, Linux, Raspberry Pi, etc.)
- Java is an object-oriented language that gives programs a clear structure and allows code to be reused, reducing development costs
- As Java is closer to C ++ and C #, this makes it easier for programmers to switch to Java or vice versa.
