java - 在Jlist中获取String的值

在这种情况下，如何获取已添加到JList中的字符串项目的项目值？我的意思是V

String[] coinNames ={"Quarters","Dimes","Nickels","Pennies"};
JList coinList = new JList (coinNames);
coinList[0] == "Quarters" ???????

由于我显然无法像普通数组一样引用它，我该如何获取coinlist [0]的字符串值？

最佳答案

这是一个简单的示例，仅获取您的JList的索引并显示所有JList。

public static void main(String[] args) {
    String[] coinNames ={"Quarters","Dimes","Nickels","Pennies"};
    JList coinList = new JList (coinNames);
    String myCoin = (String) coinList.getModel().getElementAt(0);
    System.out.println(myCoin);

    /* LIST AL YOUR COINNAMES */

    System.out.println("\nCoinList\n");

    for(int i =0; i < coinList.getModel().getSize(); i++){
        System.out.println((String) coinList.getModel().getElementAt(i));
    }

    coinNames[0] = "My new Value"; // Edit your CoinNames at index 0

    /* LIST AL YOUR NEW COINNAMES */

    System.out.println("\nNew coinList edited\n");

    for(int i =0; i < coinList.getModel().getSize(); i++){
        System.out.println((String) coinList.getModel().getElementAt(i));
    }
}
