A programming language isn't in it self open source or not, but an implementation of it might be. Yes, there are open source implementations of Java. Sun's Java implementation (the most popular one), is one of them.

The phrase "Java Programming Language" refers to the specification as provided by Sun (now oracle). Sun provides a reference implementation of Java Virtual Machine and Java Compiler. Both of which are not open source (at least not fully like say Python). 

However OpenJDK for example is a complete open-source implementation of JAVA programming language. There might be more as well.

Most of the programmers think of Java as a programming language provided by Sun. I think Sun only provides the language specification implementation can be done by anyone under any license.

From Oracle America Inc v. Google LLC No. 3:10-cv-03561-WHA:

"...
At issue in this appeal are 37 API packages from Java SE Version 1.4 and Version 5.0. We have already concluded that the declaring code and the SSO of the 37 Java API packages at issue are entitled to copyright protection. 
 Oracle, 750 F.3d at 1348. The Java programming language itself is free and available for use without permission. At this stage, it is undisputed that, to write in the Java programming language, “62 classes (and some of their methods), spread across three packages within the Java API library, must be used. Otherwise the language itself will fail.” Order Denying JMOL, 2016 WL 3181206, at *5. It is also undisputed that anyone using the Java programming language can write their own library of prewritten programs to carry out various functions. Although Oracle makes the Java platform freely available to programmers building applications (“apps”), it devised a licensing scheme to attract programmers while simultaneously commercializing the platform. In relevant part, Oracle charges a licensing fee to those who want to use the APIs in a competing platform or embed them in an electronic device. To preserve the “write once, run anywhere” philosophy, Oracle imposes strict compatibility requirements on licensees. Oracle, 750 F.3d at 1350. Oracle also made available without charge under an open source license a version of Java called “OpenJDK.” Order Denying JMOL, 2016 WL 3181206, at *10. Oracle maintains, however, that OpenJDK came with an important catch: any company that improved on the packages in OpenJDK had to “‘give away those changes for free’ to the Java community.” Appellant Br. 53. The evidence showed that Oracle licensed Java in 700 million PCs by 2005. Although Oracle never successfully developed its own smartphone platform using Java, it licensed Java SE for mobile devices. According to Oracle, the “mobile device market was particularly lucrative,” and 
 ORACLE AMERICA, INC. v. GOOGLE LLC 10 
“Java quickly became the leading platform for developing and running apps on mobile phones.” Appellant Br. 9. 
..." 

Parts of the language are subject to license fees, so those sections don't appear to be "open source"...

I know that Python, Ruby, Perl are all open source, but is Java really an open source programming language?

I have been searching on Google too, but I didn't find a proper answer.

Is java an open source programming language?

虚拟机

编译器

Eclipse

Python

Java

Perl

我知道Python、Ruby、Perl都是开源的，但是Java真的是开源编程语言吗？我也一直在谷歌上搜索，但我没有找到合适的答案。
