Here is an example that stores employee data into an arraylist and display the data of the particular employee according to the id entered by the user.

import java.util.*;
class EmployeeData 
{
    String name;
    String address;
    int id;
    EmployeeData(String name,String address,int id){
        this.name=name;
        this.address=address;
        this.id=id;
    }
    public String getName(){
        return name;
    }
    public String getAddress(){
        return address;
    }
    public int getId(){
        return id;
    }

    public static void main(String []args){
        ArrayList<EmployeeData> list=new ArrayList<EmployeeData>();
        list.add(new EmployeeData("A","Delhi",2));
        list.add(new EmployeeData("B","Mumbai",1));
        list.add(new EmployeeData("C","Agra",4));
        list.add(new EmployeeData("D","Kolkata",3));
        list.add(new EmployeeData("E","Goa",5));
        list.add(new EmployeeData("F","Chennai",8));
        list.add(new EmployeeData("G","Lucknow",7));
        list.add(new EmployeeData("H","Mathura",10));
        list.add(new EmployeeData("I","Delhi",6));
        list.add(new EmployeeData("J","Kanpur",9));

        Scanner input=new Scanner(System.in);
        System.out.print("Enter id: ");
        int i=input.nextInt();
        for(EmployeeData e : list){
            if(i==e.getId()){
                System.out.println(e.getName()+" \t "+e.getAddress()+" \t "+e.getId());
            }
        }
    }
}
