如何按值设置选定的索引 JComboBox

我想在JComboBox中按值而不是索引设置选定的索引。如何做到这一点？例

public class ComboItem {

    private String value;
    private String label;

    public ComboItem(String value, String label) {
        this.value = value;
        this.label = label;
    }

    public String getValue() {
        return this.value;
    }

    public String getLabel() {
        return this.label;
    }

    @Override
    public String toString() {
        return label;
    }
}

JComboBox test = new JComboBox();
test.addItem(new ComboItem(0, "orange"));
test.addItem(new ComboItem(1, "pear"));
test.addItem(new ComboItem(2, "apple"));
test.addItem(new ComboItem(3, "banana"));
test.setSelectedItem("banana");

好的，我已经修改了我的问题。我忘记了我的JComboBox中有一个自定义项目，这使得它变得更加困难。我不能做 setSelectedItem，因为我在每个项目内都有一个 ComboItem。那么，我该如何完成这项工作呢？
