Reflection 和 MethodHandler 机制本质上都是在模拟方法调用,Reflection 是 java 代码级别的模拟,MethodHandler 是字节码级别的模拟.在 java.lang.invoke 包下的 MethodHandlers.LookUp(内部类)有 3 个重载的方法,findStatic,findVirtual,findSpecial3 个方法正是对应 invokeStatic,invokeVirtual,invokeSpecial 三个字节码指...

Sorting is the process of arranging the elements of a collection in a specific order. In Java, thejava.util.Listinterface provides thesort()method, which can be used to sort a mutable list. However, since immutable lists cannot be modified, we need a different approach to sort them. Theja...

ImmutableListMultimap<Integer,Employee>employeeMap=Multimaps.index(duplicateEmployeeList,Employee::id); 3. Conclusion We have learned the various ways by which we can convert a List into a Map in Java. We have covered both scenarios where a List contains unique elements as well as when aListcon...
