    <p>I have 2 arraylist which the records are stored as objects.<br> First arraylist object has attributes such as patient id , totaltestcost, totaltreatmentcost. Second arraylist object has attributes such as patient id, totalservicecharges.</p> <p>Now my problem is when i try to add up the total, meaning totaltestcost + totaltreatmentcost + totalservicecharges, for a given patient id, i cant add up the total and display it. </p> <p>I found out that that since it is in 2 arrays i need to search the arrays by the id and get the costs.</p> <p>This is the way how i search a patient record public patient_class searchrecord(ArrayList patients, String search) {</p> <pre><code> for(patient_class patient: patients) //used enhanced for loop if(patient.getid().equals(search)) { return patient; } return null; </code></pre> <p>}</p> <p>Is there a possibility which i can modify this code to get the costs stored in 2 arrays ?</p> <p>for example like this :-</p> <p>public int searchrecord(ArrayList patients, String search) {</p> <pre><code> for(patient_class patient: patients) //used enhanced for loop if(patient.getid().equals(search)) { int total= patient.gettotaltestcost + patient.gettotaltreatmentcost } return null; </code></pre> <p>} But if i use the above method ill only be able to get the total of totaltestcost+totaltreatmentcost , i need to obtain the servicechargecost as well but its in another array.</p> <p>So how can i do this ?</p> <p>Thank you for your time.</p> <p>Edit :-</p> <p>Finally i managed to do it guys and here is how i did it :-</p> <p>public String addtotal(ArrayList patients, String search,ArrayListpatient2,String search2) { int total;</p> <pre><code> for(patient_class patient: patients) //used enhanced for loop { if(patient.getid().equals(search)) { for(patient_class patient3: patient2) { if(patient3.getid().equals(search2)) { total=patient.gettreatmentcost()+patient.gettestcost()+patient3.getservicecharge(); return Double.toString(total); } } } } return null; </code></pre> <p>}</p> <p>i passed in both arrays at once.</p> <p>Thanks everyone for sharing your answers , next time ill definitely use treemaps </p>

    1. COIn my opinion you are using the wrong datastructure for the job. A map structure where the patient id is the key and the value is the patient object would be suited much better for the job. It would allow a cost of O(1) on lookup.

    3. COWell, I'd like to help, but i would need some more info on the second array. I only see 1 array describing a list of patients. But I have no idea what the second one looks like. Is this second list also a patient list, and if so, what method are we looking for?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
