如何獲得所選擇的指數時JList的多個數據從另一個文件選擇

Question

try{ 
    f = new ProjectFile(); 

    numProject = f.getOutput(); 

    String[] projectData = new String[numProject.length]; 

//檢索數據和標題存儲ProjectData的

 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.
