Error message when trying to install rJava

I am trying to install rJava but it is not working. No matter which version of Java I install, I always get the same error. I already tried to install previous Java versions but that is not working. I also tried to set JAVA_HOME to the JDK folder but nothing seems to work. I am using Windows10. Code and error:

> install.packages("rJava")
Installing package into ‘C:/Users/x/Documents/R/win-library/3.6’
(as ‘lib’ is unspecified)

  There is a binary version available but the source version is later:
      binary source needs_compilation
rJava 0.9-12 0.9-13              TRUE

I would not recommend installing rJava from sources, because it is entirely unnecessary and compiling packages on Windows requires much better knowledge of tools, Java and your system. Since you are using Windows, please install rJava from CRAN using

install.packages("rJava", type="win.binary")
