Define a constant instead of duplicating "http://loinc.org" 3 times

I tried defining a const by typing in
const loinc = "http://loinc.org";

After pushing my code, the build fails and I get this error: illegal start of expression

List<ObservationComponentComponent> listComponent = new ArrayList<>();
        // loop through the different types in array 
        for (int i = 0; i < body.length; i++) {
            DeviceBloodPressureBody curBody = body[i];
            ObservationComponentComponent component = new ObservationComponentComponent();
            // set LOINC codes for components
            CodeableConcept observationComCodeConcept = new CodeableConcept();
            Coding observationComCodeCoding = new Coding("", "", "");
            const loinc = "http://loinc.org";
            if (curBody.getDataType().equals("diastolic")) {
                observationComCodeCoding = new Coding(loinc, "88462-4", "Diastolic blood pressure");
            } else if (curBody.getDataType().equals("systolic")){
                observationComCodeCoding = new Coding(loinc, "8480-6", "Systolic blood pressure");
            } else if(curBody.getDataType().equals("pulse")){
                observationComCodeCoding = new Coding(loinc, "8867-4", "Heart rate");
            }
            observationComCodeConcept.addCoding(observationComCodeCoding);
            component.setCode(observationComCodeConcept);

>Solution :

That way of defining a constant is for Javascript, not Java.

You can define one by changing

const loinc = "http://loinc.org";

For

final String loinc = "http://loinc.org";
