我有4个数组，想要排列子列表：
String[] subject_code = {"160","160","161","161","161","162","162","164","164","164","163","163"};
String[] external_marks = {"DNR","50","DNR","SA","60","DNR","55","DNR","52","22","DNR","65"};
String[] result =
{"--","Pass","--","---","Pass","--","Pass","--","Pass","Fail","--","Pass"};
String[] date_of_exam = {"--","2018-06-28","--","---","2018-06-28","--","2018-06-28","--","2018-12-15","2018-06-28","--","2018-06-28"};
条件： 在external_marks []数组中，SA应该排在第一位，然后是DNR，最后是按尝试日期在该subject_code子列表（根据条件排列子列表）上按升序排列的标记
示例- 看看161个主题代码的子列表应该是这样的：
161","161","161
"SA","DNR","60"
"---","--","P"
"---","--","2018-06-28"
最终名单如下：
String[] subject_code = {"160","160","161","161","161","162","162","164","164","164","163","163"};
String[] external_marks = {"DNR","50","SA","DNR","60","DNR","55","DNR","22","52","DNR","65"};
String[] result = {"--","Pass","---","--","Pass","--","Pass","--","Fail","Pass","--","Pass"};
String[] date_of_exam = {"--","2018-06-28","---","--","2018-06-28","--","2018-06-28","--","2018-06-28","2018-12-15","--","2018-06-28"};
请帮助我根据上述条件对数组子列表进行排序
