public class Main5 {

    public static void main(String[] args) {
        String expression = "a>10 || a==5";
        Expression compile = AviatorEvaluator.compile(expression);
        Map<String, Object> map = new HashMap<>();
        map.put("a", 5);
        Boolean execute = (Boolean)compile.execute(map);
        System.out.println(execute.toString());
        // out => true
