我正在使用Java-8 lambda对列表进行排序.

这是列表

[(t1, tester1), (t4, tester4), (t3, tester3), (t2, tester2)]

[(t2, tester2), (t1, tester1), (t3, tester3), (t4, tester4)]

我想得到如上所述的结果

String specialId = 't2'

List<Test> list = new ArrayList<>();

Test test1 = new Test();
test1.setId = "t1"
test1.setName = "tester1"
list.add(test1)

Test test2 = new Test();
test2.setId = "t4"
test2.setName = "tester4"
list.add(test2)

Test test3 = new Test();
test3.setId = "t3"
test3.setName = "tester3"
list.add(test3)

Test test4 = new Test();
test4.setId = "t2"
test4.setName = "tester2"
list.add(test4)

Stream<Test> s1 …
