如何从下拉列表中选择字符串，并将其传递给具有字符串数组的对象类

比如说

在职班

JComboBox comboBox = new JComboBox();
    for (int i = 0; i < 3; i++)
    {
        comboBox.addItem(Rma.warrantyStatus[i]);    
    }
    comboBox.setBounds(123, 57, 116, 20);
    Add.add(comboBox);

String[] warrantyStatus = {"In warranty", "Out of warranty", "DOA"};

public String[] getWarrantyStatus() {
    return warrantyStatus;
}
public void setWarrantyStatus(String[] warrantyStatus) {
    this.warrantyStatus = warrantyStatus;
