用java定义一个股票类Stock,该类包括如右图所示

public class Stock {

private String store;// 股票类属性

private String symbol;// 股票代号

private String name;// 股票名称

private BigDecimal currentPrice;// 当前时间的股票价格

private BigDecimal previouClosingPrice;// 前一天的股票值

/**

* 返回前一天变到当前时间的百分比

* @return 百分比

*/

public double getChangePercent() {

return this.currentPrice.subtract(this.previouClosingPrice).abs()

.divide(this.currentPrice, 2, BigDecimal.ROUND_HALF_EVEN)

.doubleValue();

}

/**

* 返回前一天变到当前时间的百分比

* @param currentPrice 当前时间的股票价格

* @param previouClosingPrice 前一天的股票值

* @return 百分比

*/

public double getChangePercent(BigDecimal currentPrice,

BigDecimal previouClosingPrice) {

return currentPrice.subtract(previouClosingPrice).abs()

.divide(currentPrice, 2, BigDecimal.ROUND_HALF_EVEN)

.doubleValue();

}

public String getStore() {

return store;

}

public void setStore(String store) {

this.store = store;

}

public String getSymbol() {

return symbol;

}

public void setSymbol(String symbol) {

this.symbol = symbol;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public BigDecimal getCurrentPrice() {

return currentPrice;

}

public void setCurrentPrice(BigDecimal currentPrice) {

this.currentPrice = currentPrice;

}

public BigDecimal getPreviouClosingPrice() {

return previouClosingPrice;

}

public void setPreviouClosingPrice(BigDecimal previouClosingPrice) {

this.previouClosingPrice = previouClosingPrice;

}

}

拥有java基础,怎样编写一个股票分析软件

你得有选股的算法,实时调取所有股票所有信息的途径。。。然后就可以做了

java 谁能给我画图组成的股市分析代码?

如何用java读取股票数据

股票实时行情,可以通过两个方法来进行查看: 第一种,在百度搜索页面直接输入股票代码,如:000717,百度输入后,即可在搜索结果中看到,其中分时,就是该股票在当天的实时走向。 第二种,通过炒股软件,如东财,同花顺等,在开启后,直接输入
