过滤二维数组/返回 ArrayIndexOutofBoundException

Question

这是我的二维数组和单个数组的结构

public String[] sList() {
    String list[] = { "Asia Medic Family Hospital and Medical Center",
            "Adventist University of the Philippine Health Service ",
            "Bautista Hospital",
            "Catalan Medical Hospital ", 
            "Catbagan General Hospital",
            "Cavite Center for Mental Health", 
            "Cavite Doctors' Medical Center, Inc",
            "Cavite Medical Center", 
            "Cavite Municipal Hospital",
            "Cavite Naval Hospital", 
            "Contreras Medical Clinic",
            "Crisostomo General Hospital", 
            "DBB Municipal Hospital",
            "DLSU-Dr. Rodolfo Poblete Memorial Hospital ", 
            "De La Salle University Medical Center",
            "Del Rosario Hospital" };
return list;
.....
public String[][] sSpecialty() {
    String list[][] = { 



            {"Specialty 1.0", "Specialty1.1", "Specialty1.2" , " " , " " },
            {"Specialty 2.0", "Specialty2.1", "Specialty2.2" , " " , " "},
            {"Specialty 3.0", "Specialty3.1", "Specialty3.2", "Specialty3.3", " " },
            {"Specialty 4.0", "Specialty4.1", "Specialty4.2", "Specialty4.3", "Specialty4.4" },
            {"Specialty 5.0", "Specialty5.1", "Specialty5.2", "Specialty5.3", "Specialty5.4" },
            {"Specialty 6.0", "Specialty6.1", "Specialty6.2", "Specialty6.3", "Specialty6.4" },
            {"Specialty 7.0", "Specialty7.1", "Specialty7.2", "Specialty7.3", "Specialty7.4" },
            {"Specialty 8.0", "Specialty8.1", "Specialty8.2", "Specialty8.3", "Specialty8.4" },
            {"Specialty 9.0", "Specialty9.1", "Specialty9.2", "Specialty9.3", "Specialty9.4" },
            {"Specialty 10.0", "Specialty10.1", "Specialy10.2", "Specialty10.3", "Specialty10.4" },
            {"Specialty 11.0", "Specialty11.1", "Specialty11.2", "Specialty11.3", "Specialty11.4" },
            {"Specialty 12.0", "Specialty12.1", "Specialty12.2", "Specialty12.3", "Specialty12.4" },
            {"Specialty 13.0", "Specialty13.1", "Specialty13.2", "Specialty13.3", "Specialty13.4" },
            {"Specialty 14.0", "Specialty14.1", "Specialty14.2", "Specialty14.3", "Specialty14.4" },
            {"Specialty 15.0", "Specialty15.1", "Specialty15.2", "Specialty15.3", "Specialty15.4" },
            {"Specialty 16.0", "Specialty16.1", "Specialty16.2", "Specialty16.3", "Specialty16.4" }
};
return list;

我如何过滤这些二维数组，例如当我选择 Specialty2.2 时，我在这里有一个项目，结果是菲律宾卫生服务复临大学，你可以看到它们都在第二个数组列表中。我对单个数组进行精细过滤，但在添加二维数组时遇到问题。

for (int loop = 0; loop < sList.length; loop++) {
        String temp = sTuition[loop];
        theTuitionFee = Integer.parseInt(temp);

        // ALL filter selected
        if (sReg[loop].equalsIgnoreCase(thisFilter[0])
                && sAdmin[loop].equalsIgnoreCase(thisFilter[1])
                && sAmbience[loop].equalsIgnoreCase(thisFilter[3])
                && amountTF >= theTuitionFee
                && sSpecialty[loop][loop].equalsIgnoreCase(thisFilter[5])
                ) {
            list.add(sList[loop]);

我在这部分“ && sSpecialty[loop][loop].equalsIgnoreCase(thisFilter[5]) ”中得到 ArrayIndexOutofBoundsException 任何建议如何解决这个问题。

如果您有任何其他方式添加创建的二维数组，这是我只使用单个数组时的完整程序。

public class SchoolListFragmentFilter extends Fragment implements
    OnItemClickListener {
NavigationDrawer navi = new NavigationDrawer();
String thisFilter[] = NavigationDrawer.theFilter;
int amountTF = NavigationDrawer.TuitionFee;
PSManilaDB conn = new PSManilaDB();
String sList[] = conn.sList();
String sReg[] = conn.sRegAffil();
String sAdmin[] = conn.sAdmin();
String sType[] = conn.sSize();
String sAmbience[] = conn.sAmbience();
String sTuition[] = conn.sTuitionFee();
int theTuitionFee;

Answer 1

如果我理解正确，sList.length 是 16，但你的二维数组宽度只有 5。这意味着 loop 上升到 16，但 sSpecialty[loop][loop] 中的第二个索引必须小于 5。这是您在哪里获得 IndexOutOfBoundsException。

我想你需要用类似的东西替换 if 语句

// ALL filter selected
boolean filtermatch=false;

for(int subloop=0;subloop<sSpecialty[loop].length;subloop++){
        if (sSpecialty[loop][subloop].equalsIgnoreCase(thisFilter[5])
                ) {
                   filtermatch=true;
        }
}

if(filtermatch && sReg[loop].equalsIgnoreCase(thisFilter[0])
                && sAdmin[loop].equalsIgnoreCase(thisFilter[1])
                && sAmbience[loop].equalsIgnoreCase(thisFilter[3])
                && amountTF >= theTuitionFee;){
    list.add(sList[loop]);
}

第二个循环将第二个索引保持在界限内。
