Java 如何对值最低的arraylist对象进行排序？ ArrayList aithird=new ArrayList（）； ShyForeignStockHolding shyfrst=新的ShyForeignStockHolding（shyPurchaseSharePrice、shyCurrentSharePrice、shyNumber of Shares、shyCompanyName、shyconversionRate1）； aithird.add（shyfrst）；

我想按

Currentshare Price

对

ArrayList

排序您可以使用对象的自定义

比较器，假设您对
shyCurrentSharePrice
使用double：

ArrayList <ShyForeignStockHolding> aithird = new ArrayList<ShyForeignStockHolding>();

ShyForeignStockHolding shyfrst = new ShyForeignStockHolding (shyPurchaseSharePrice, shyCurrentSharePrice, shyNumberOfShares, shyCompanyName, shyconversionRate1);

aithird.add(shyfrst);

List sFSH=new ArrayList（）；
//添加您的对象
Collections.sort（sFSH，newcomparator（）{
@覆盖公共双比较（ShyForeignStockHolding ssh1、ShyForeignStockHolding ssh2）{
返回ssh1.shyCurrentSharePrice+shh2.shyCurrentSharePrice；//降序使用-升序使用
}
});
使用Java 8，您现在可以像这样轻松地创建比较器（完全避免匿名类）。因为这是按升序排列的，所以可以在该比较器上调用
reversed（）
，使其降序

List<ShyForeignStockHolding> sFSH = new ArrayList<ShyForeignStockHolding>();
//add Your objects
Collections.sort(sFSH, new Comparator<ShyForeignStockHolding>() {
    @Override public double compare(ShyForeignStockHolding ssh1, ShyForeignStockHolding ssh2) {
        return ssh1.shyCurrentSharePrice + shh2.shyCurrentSharePrice; //descending use - for Ascending
    }

});

Comparator Comparator=Comparator.comparating（（sh->sh.getTheVarYouWantToCompareBy（））.reversed（）；
aithird.sort（比较器）；
shyCurrentSharePrice是浮点型变量。你可以使用java比较器来实现你想要的。你能给我一些提示吗？或者举个例子？
Comparator<ShyForeignStockHolding> comparator = Comparator.comparing((sh -> sh.getTheVarYouWantToCompareBy())).reversed();
aithird.sort(comparator);
