How can values in a JS array be populated from a Java method returning a list?

Foo.java

//getters of java class

        //returns [0] = "something, -33.89, 151.2" [1] = "beach, -33.9, 15.02" etc.
	public List<String> getVals() {
		return vals;
	}

	public String getGoogleClass() {
		if (vals.size() == 0)
			return "";
		return "map_canvas";
	}
