Explanation / Answer

I have written the java code for both the problem.

working java code compiled on ideone:

/* package whatever; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Ideone
{
  
   String name;
   String phone_num;
   public String getname()
   {
       return name;
   }
   public String getphone()
   {
       return phone_num;
   }
   public void setname(String n)
   {
       name=n;
   }
   public void setphone(String p)
   {
       phone_num=p;
   }
  
   public class NameComparator implements Comparator<Ideone>
{
public int compare(Ideone o1, Ideone o2)
{
return o1.getname().compareTo(o2.getname());
}
}

   public class PhoneComparator implements Comparator<Ideone>
{
public int compare(Ideone o1, Ideone o2)
{
return o1.getphone().compareTo(o2.getphone());
}
}
  
   public static void main (String[] args) throws java.lang.Exception
   {
       Ideone[] a = new Ideone[10];
      
       // your code goes here
   }
}
