transaction.java

挺好的JAVA例子,可用MYSQL,ACCESS,ORACLE做后台,例子中包括联结及查询等涵数

public class Transaction {

	public void setFields(int tID, int cID, int amt, String dt, String desc) {
	    transactionID = tID;
	    clientID = cID;
	    amount = amt;
	    date = dt == null ? null : new String(dt);
	    description = desc == null ? null : new String(desc);
	}

    public int transactionID;
    public int clientID;
    public int amount;		//amounts stored in cents
    public String date;
    public String description;
    
    public String dollarAmount() {
		boolean neg = false;
		int amt = amount;
		if (amt < 0) {
			neg = true;
			amt = -amt;
		}
		int dollars = amt / 100;
		int cents = amt % 100;
		return (neg ? "-" : "")
			+ dollars
			+ "."
			+ (cents < 10 ? "0" : "")
			+ cents;
    }
    
	public String toString() {
        return "Transaction: " + transactionID + " with client " + clientID + " for " + amount + " on " + date + ". " + description;
	}
}
