We use simple Java program: Create file Check.java , complie by javac tool and run this by java tool (these tools in directory %JAVA_HOME%\bin )

public class Check {
    public static void main(String[] args) {
        System.out.println("Java Runtime Environment version is " + System.getProperty("java.version"));
    }

}

//        Result:
//        Java Runtime Environment version is 1.8.0_20

None of the versions you've listed are Java 8 for linux. The closest is openjdk-7-jre-headless, but that's Java 7. The gcj is part of gcc. To determine the version in Windows you can run,

java -version

or

java -fullversion
