What other languages do you know? If you know something with similar enough syntax (C++, C#, Javascript, etc.), even if the semantics aren't the same, you should be ok getting the basic idea of the Java code in the book, especially considering how he explains things as you go. Then just write it in whatever language you want. When I went through the first half of the book back in 2017, I wrote it in Scala. (I did know Java, too, though, so certainly I had an easier time understanding the code examples in the book.)
