In your Java application you may want to run another Java application. In order to do this, you need to know where is the bin/java executable. It's in the JAVA_HOME (environment variable), which is not always set. Instead of looking for this place manually, just use this small one-class library.

First, you add this to your pom.xml:

<dependency>
  <groupId>com.yegor256</groupId>
  <artifactId>jhome</artifactId>
  <version>0.0.3</version>
</dependency>

Then, you use it like this:

import com.yegor256.jhome;
Path p = new Jhome().path("bin/java");

The result is the location of bin/java inside JAVA_HOME. Also, you can use java() and javac() methods in order to get the full path to java and javac executables respectively:

import com.yegor256.jhome;
Path java = new Jhome().java();
Path javac = new Jhome().javac();
