//代码是楼上的，帮你排了一下版。


public class Account {
	private int id;
	private double balance;
	private double annuallnterestRate;
	private Date dateCreated;

	public Account() {
		this.id = 0;
		this.balance = 0;
		this.annuallnterestRate = 0;
		this.dateCreated = new Date();
	}

		this.id = id;
		this.balance = balance;

	}

	public Date getDateCreated() {
