Sort Array list using POJO class with particular status

Question

I have status like "In consultation","Waiting in Queue". all the data coming from json API and add all that data into array list using Pojo class.then how to sort this array list by Consultation status.

Patient Class:

public class Patient_Get_Set implements Serializable {
private String fullName;
private String age;
private String waitTime;
private String sex;
private String patientID;
private String gender;
private String dateOfBirth;
private String phoneNo;
private String Diagnosis;
private String Email;
private String token_id;
private String priority;
private String consultation_status;
private String case_number;

public String getCase_number() {
    return case_number;
}

public void setCase_number(String case_number) {
    this.case_number = case_number;
}

public String getConsultation_status() {
    return consultation_status;
}

public void setConsultation_status(String consultation_status) {
    this.consultation_status = consultation_status;
}

public String getPriority() {
    return priority;
}

public void setPriority(String priority) {
    this.priority = priority;
}

public String getToken_id() {
    return token_id;
}

public void setToken_id(String token_id) {
    this.token_id = token_id;
}

public String getConsultationstatus() {
    return consultationstatus;
}

public void setConsultationstatus(String consultationstatus) {
    this.consultationstatus = consultationstatus;
}

private String consultationstatus;

public String getEmail() {
    return Email;
}

public void setEmail(String email) {
    Email = email;
}

public String getVisitorType() {
    return visitorType;
}

public void setVisitorType(String visitorType) {
    this.visitorType = visitorType;
}

private String visitorType;


public String getDiagnosis() {
    return Diagnosis;
}

public void setDiagnosis(String diagnosis) {
    Diagnosis = diagnosis;
}

private String patientJsonArray;

public void setFullName(String fullName) {
    this.fullName = fullName;
}

public void setAge(String age) {
    this.age = age;
}

public void setWaitTime(String waitTime) {
    this.waitTime = waitTime;
}

public String getFullName() {
    return fullName;
}

public String getAge() {
    return age;
}

public void setSex(String sex) {
    this.sex = sex;
}

public String getSex() {
    return sex;
}

public String getWaitTime() {
    return waitTime;
}


public void setPatientID(String patientID) {
    this.patientID = patientID;
}

public void setGender(String gender) {
    this.gender = gender;
}

public void setDateOfBirth(String dateOfBirth) {
    this.dateOfBirth = dateOfBirth;
}

public String getDateOfBirth() {
    return dateOfBirth;
}

public void setPhoneNo(String phoneNo) {
    this.phoneNo = phoneNo;
}

public String getPhoneNo() {
    return phoneNo;
}

public String getPatientID() {
    return patientID;
}

public void setPatientJsonArray(String patientJsonArray) {
    this.patientJsonArray = patientJsonArray;
}

public String getPatientJsonArray() {
    return patientJsonArray;
}


public String getGender() {
    return gender;
}
}

You could either implement [Comparable](https://docs.oracle.com/javase/7/docs/api/java/lang/Comparable.html) or create a custom [Comparator](https://docs.oracle.com/javase/7/docs/api/java/util/Comparator.html) for your Pojo sorting by consultation status. Then you can use the sort method of [Collections](https://docs.oracle.com/javase/6/docs/api/java/util/Collections.html) for your ArrayList which holds Patient_Get_Set objects. — BrickTop, Apr 13 '17 at 08:46

Here is code what you can use for your custom need -

Collections.sort(list, new Comparator<Patient_Get_Set>() {
        @Override
        public int compare(final Patient_Get_Set object1, final Patient_Get_Set object2) {
            List<String> statusList = new ArrayList();
            statusList.add("consultation");statusList.add("queue"); statusList.add("waiting");
            return new Integer(statusList.indexOf(object1.getConsultation_status())).compareTo(new Integer(statusList.indexOf(object2.getConsultation_status())));
            }
        });

add elements in statusList in same order in which order you want pojo class to be sorted.

its working fine.ty – Damini Mehra Apr 13 '17 at 11:09

You can use Collections to sort your array list objects.

for example your list as below.

ArrayList<Patient> list = new ArrayList<Patient>();

Then you can sort list using below code.

  Collections.sort(list, new Comparator<Patient>() {
      @Override
      public int compare(final Patient object1, final Patient object2) {
          return object1.getConsultation_status().compareTo(object2.getConsultation_status());
      }
  });

OR

If you are using Java version 1.8 then you can sort list using below code.

list.stream()
.sorted((object1, object2) -> object1.getConsultation_status().compareTo(object2.getConsultation_status()));

@DaminiMehra Means you want to divide your full list into two separate lists, like list of patient in queue and in waiting ? – Priyank Patel Apr 13 '17 at 09:13
no, i need only one list but first item status is in consulation then another status – Damini Mehra Apr 13 '17 at 09:51
@DeepakTripathi ok i will implement and told you after some time – Damini Mehra Apr 13 '17 at 10:34

import static java.util.Comparator.comparing;

Collections.sort(list, comparing(MyObject::getStartDate));

compare data with comparing in java8 follow http://docs.oracle.com/javase/6/docs/api/java/lang/Comparable.html
