Question

I have an ArrayList which contains data like profId, firstname, lastname, age.

Now I have a lastname and firstname, which gets from user form side. Now I want to compare them with an ArrayList. If both match, I want to retrieve “respective profId”.

e.g arraylist contains data like

profId lastname fistname age

1 roy sam 25

2 ryob arnav 30

Now user will type lastname and firstname as roy and sam respectively. I will get this data by their getter methods.

Now, how should I compare these 2 names with the ArrayList so that I will get the perfect profid of him as:

‘1’.

I am trying to compare by this way.

//  existPatList is arraylist patfamily is object of Family from where I will get users value

for(Family p : existPatList) {
    System.out.println("Last name" +p.getLastName());             
    System.out.println("First name"+p.getFirstName());
    if(p.getLastName().equalsIgnoreCase(patFamily.getLastName())) {
        System.out.println("got it");       
    }
}

How can I solve this problem?

Answer 1

Use a && in your if condition with both firstName and lastName.

for(Family p : existPatList) {
   System.out.println("Last name" +p.getLastName());             
   System.out.println("First name"+p.getFirstName());
   if(p.getFirstName().equalsIgnoreCase(patFamily.getFirstName()) && p.getLastName().equalsIgnoreCase(patFamily.getLastName())) {
       System.out.println("got it");       
   }
}

To get profId replace your line:

System.out.println("got it");

with

System.out.println(p.getProfId); //or do whatever you wanna do with profId

I consider here the you getters also has a get method for profId, that is getProfId()
