如何在选择 JList 中的多个数据时获取所选索引号

Question

    try{
    f = new ProjectFile();
    numProject = f.getOutput();
    String[] projectData = new String[numProject.length];

从另一个文件中检索数据并将标题存储到 projectData

        for (int i = 0; i < projectData.length; i++) {
            projectData[i] = numProject[i].getProjectTitle();
        }
        listProject.setListData(projectData);
        System.out.println(listProject.getSelectedIndex());
}catch(Exception e){
}

Answer 1

使用getSelectedIndices()方法

public int[] getSelectedIndices()
Returns an array of all of the selected indices, in increasing order.
