Showing users input History

Question

I'm new to java. I have this codes for an ATM with deposit, withdraw, balance and history option.. and now my problem is the history option.. I really don't know how to make all users input into it.. I try making one but it only shows 1 history of the last input...

package atm;

import java.util.ArrayList;
import java.util.Scanner;
public class Atm {

    static Scanner input = new Scanner(System.in);
    static int choose,back;
    static double withdraw,balance,deposit,depos,post;

    static int []array;
    public static void main(String[] args) {
        System.out.println("\t Welcome Visitors");
        start();
    }//end of main
    public static void hello(){
        System.out.println("\t\tHello: "+username);
        options();
    }
    public static void start(){
        try{
            System.out.println("\t Username: ");
            us=input.nextLine();
            if(us.equalsIgnoreCase(username)){
                password();
            }
            else{
                System.err.println("Incorrect Username");
                start();
            }
        }//end of try
        catch(Exception a){
            System.err.print("\t Invalid Input");

For history you need to keep two arrays, one for keeping last transaction type (deposit, withdrawal) that changed the balance and another for the amount of the transaction. And tha array size could be constrained by a upper limit as well (say 10). So, that means at most 10 history items you would remember. Then you need to manage the chronology (sequence) of history items within that bounded set.
