Solution

Account.java

public abstract class Account {
   protected int account_number;
   protected double balance;
   public Account(int account_number) {
       super();
       this.account_number = account_number;
       this.balance = 0.0;
   }

   public abstract int getAccountNumber();
   public abstract double getBalance();
   public abstract void getAccInfo();
  
   public void setBalance(double bal)
   {
       this.balance=bal;
   }
  

}

Checking.java

public class Checking extends Account {

       return account_number;
   }

   @Override  
   public double getBalance() {
       return balance;
   }

   @Override
   public void getAccInfo() {
       System.out.println(\"Checking Account Information \"+getAccountNumber()+\" and the balance $\"+getBalance());

   }

}

Savings.java

public class Savings extends Account {

   private double rate;
  
   public Savings(int account_number, double rate) {
       super(account_number);
       this.rate = rate;
   }

   @Override
   public int getAccountNumber() {
  
       return account_number;
   }

   @Override
   public double getBalance() {
      
       return balance;
   }

   @Override
   public void getAccInfo() {
   System.out.println(\"Savings Account Information \"+getAccountNumber()+\" and the balance $\"+getBalance()+\" Rate:\"+rate);

   }

}

       Account arr[]= new Account[10];
       arr[0]= new Checking(111);
       arr[0].setBalance(3000);
       arr[1]=new Savings(123,3.5);
       arr[1].setBalance(2000);
       arr[2]=new Checking(222);
       arr[2].setBalance(1500);
       arr[3]=new Savings(234,4.5);

arr[7].setBalance(4500);
arr[8]=new Checking(555);
arr[8].setBalance(4200);
arr[9]=new Savings(567,3.7);
arr[9].setBalance(4500);

       for(int i=0;i<arr.length;i++)
       {
