Explanation / Answer

Requirements are not clear and document is not attached .

I assume you want to make a program for Credit Card .

So here is the code.

CreditCardAccount .java

import java.util.Scanner;

public class CreditCardAccount {

    private int cardnumber;
    private String name;
    private int creditlimit;
    int creditamount;

    //Constructor
    public CreditCardAccount(int cardnumber, String name, int creditlimit) {
        super();
        this.cardnumber = cardnumber;
        this.name = name;
        this.creditlimit = creditlimit;
        this.creditamount = 0;//initial amount
    }
    public void charges() {
        Scanner in = new Scanner(System.in);
        //int creditLimit = 500000;
        int numofdays;
        double charges = 0;

        System.out.println("Enter credit amount");
        creditamount = in.nextInt();
        System.out.println("Enter number of days ");
        numofdays = in.nextInt();
        if (numofdays < 10) {
            charges = creditamount * 0.15;
        } else if (numofdays >= 10 && numofdays < 30) {
            charges = creditamount * 0.2;
        }
        creditamount=(int) charges;
        System.out.println("charges paid " + charges);
    }

   public void payments(int cash) {

        int balance;
        balance = creditamount - cash;
        System.out.println("Blance aamount =" + balance);
    }
   @Override
   public String toString() {
       return "CreditCardAccount [cardnumber=" + cardnumber + ", name=" + name + ", creditlimit=" + creditlimit
               + ", creditamount=" + creditamount + "]";
   }
  
}

TestCreditCardAccount .java

public class TestCreditCardAccount {

   public static void main(String[] args) {

       // Creating three instances
       CreditCardAccount person1 = new CreditCardAccount(452133, "Kamal Kumar S", 1000000);
       CreditCardAccount person2 = new CreditCardAccount(452199, "tendra P", 500000);
       CreditCardAccount person3 = new CreditCardAccount(4519880, "Nagendra B", 2000000);

       // For Person 1

       // Call charges
       person1.charges();
       // call payments
       person1.payments(100);
       System.out.println(person1);

       // For Person 2

       // Call charges
       person2.charges();
       // call payments
       person2.payments(200);
       System.out.println(person2);

       // For Person 3

       // Call charges
       person3.charges();
       // call payments
       person3.payments(300);
       System.out.println(person3);
   }

}
