Issue
I want to store data as below format to any function of java collection and print the output:-
[
{ id->100, name->'praveen', mobile-9455104973 },
{ id->101, name->'Saurbh', mobile-7355078643 },
{ id->103, name->'Shivendr', mobile-123456789 }
]
Output:
ID Name Mobile
100 Praveen 9455104973
101 Saurbh 735078643
102 Shivendra 123456789
Solution
I recommend that you create an employee class.
public class Employee {
private int id;
private String name;
private long phoneNumber;
/**
* @param id
* @param name
* @param phoneNumber
*/
public Employee(int id, String name, long phoneNumber) {
super();
this.id = id;
this.name = name;
this.phoneNumber = phoneNumber;
}
@Override
public String toString() {
return id + "\t" + name + "\t" + phoneNumber + "\n";
}
}
After that you create a list of employees and initialize it with the employees you are interested in and print it.
List<Employee> employees = new ArrayList<>();
employees.add(new Employee(100, "praveen", 9455104973L));
employees.add(new Employee(101, "Saurbh", 7355078643L));
employees.add(new Employee(103, "Shivendr", 123456789L));
System.out.println("ID\tName\tMobile");
for (Employee e: employees)
System.out.println(e.toString());
OUTPUT:
ID Name Mobile
100 praveen 9455104973
101 Saurbh 7355078643
103 Shivendr 123456789
