How to overload function with "int" in Frida

I have the following function: 

public final int getState(@NotNull String str, int i) {
    Intrinsics.checkParameterIsNotNull(str, "key");
    return PreferenceManager.getDefaultSharedPreferences(this).getInt(str, i);
}

I don't know who to use the int argument when overloading. This is what I tried: 

var myapp= Java.use('com.myapp.AppActivity');
myapp.cleanUi.overload().implementation = function () {
    console.log('! Intercepted cleanUi');
}

It throw an exception:

{'type': 'error', 'description': "Error: getState(): specified argument types do not match any of:
        .overload('java.lang.String', 'java.lang.String')
        .overload('java.lang.String', 'float')
        .overload('java.lang.String', 'int')", 'stack': "Error: getState(): specified argument types do not match any of:
        .overload('java.lang.String', 'java.lang.String')
        .overload('java.lang.String', 'float')
        .overload('java.lang.String', 'int')

While writing the question I found what was the problem and I want to share it with you.

I just needed to add the arguments that I am using so just adding these str and myint: 

myapp.getState.overload('java.lang.String', 'int').implementation = function (str, myint) {
    console.log('! Intercepted getState');
    return 100;
};
