Foreach in Java basic example source code.

MainClass.java

public class MainClass {
	public static void main(String[] arg) {
		String[] arrayOfString = { "Hello", "people", "hello", "world!" };

		for (String s : arrayOfString)
			System.out.println(s);

	}
}

You can get list by class Build
For example:

if(Build.MANUFACTURER.equals("unknown")) {
		// Emulator
	}

List of Build class getting from emulator:
"BOARD=unknown
