android reflection giving no such method exception

I am trying to call a method from dex class using reflection but getting no such method exception when using arguments to call the method here is my code try {

        Class<?> wordClass = dexClassLoader.loadClass("com.example.Algorithm");
        Object iClass = wordClass.newInstance();
        Method thisMethod = wordClass.getMethod("eoiValue",String.class );

        helloTextView.setText("Hello " + thisMethod.invoke(iClass, "100").toString());

        //The above 4 lines equals below
        //helloTextView.setText("Hello " + new nfh.speeder.sample.gradle.hello.Word().speeder());

    } catch (ClassNotFoundException e) {
    } catch (NoSuchMethodException e) {
        Log.i("exception","2");
    } catch (IllegalAccessException e) {
    } catch (IllegalArgumentException e) {
    } catch (InvocationTargetException e) {
    } catch (InstantiationException e) {
    }

and the method I am calling is

public class Algorithm {

public String eoiValue (String temperature){
    String eoi = "0";
    float temp=Float.valueOf(temperature);
    if (temp<=97){
        eoi="0.1";
    }
    else if (temp<=98){
        eoi="0.2";
    }else if (temp<=99){
        eoi="0.3";
    }else if (temp<=100){
        eoi="0.3";
    }else if (temp<=101){
        eoi="0.4";
    }else if (temp<=102){
        eoi="0.5";
    }else if (temp<=103){
        eoi="0.6";
    }else if (temp<=104){
        eoi="0.7";
    }else if (temp<=105){
        eoi="0.8";
    }else if (temp<=106){
        eoi="0.9";
    }else if (temp<=107){
        eoi="1.0";
    }

    return eoi;
}

}

I always get no such method exception.
