java实验stock类

以下是Java实验Stock类的示例代码：

1. Stock类的定义

public class Stock {
    String symbol;
    String name;
    double previousPrice;
    double currentPrice;

    public Stock(String symbol, String name) {
        this.symbol = symbol;
        this.name = name;
    }

    public double getChangePercent() {
        return ((currentPrice - previousPrice) / previousPrice) * 100;
    }
}

2. TestStock类的使用

public class TestStock {
    public static void main(String[] args) {
        Stock pfyh = new Stock("600000", "浦发银行");
        pfyh.previousPrice = 25.50;
        pfyh.currentPrice = 28.60;
        System.out.println(pfyh.name);
        System.out.println(pfyh.symbol);
        System.out.printf("该股票的市值变化百分比为：" + "%.2f", pfyh.getChangePercent());
        System.out.println("%");
    }
}
