In this week's study, lambda expressions, anonymous inner classes, and local inner classes have their own understanding. They are used in callback techniques to reduce the amount of code compared to previous callbacks. This programming task has played a role in reviewing the previous knowledge. Discover the knowledge that you have not mastered before. In a program that sorts names in an identity card, the result is wrong if only arrays.sort () is used to sort the array of strings that consist of names. After querying, when an object of the Collator class is introduced in Arrays.sort () (Collator object name = Collator.getinstance (Locale.china)), It will be out of the right results but it is wrong to have names that are uncommon. The question is not quite clear about how to solve it. The use of static methods is mastered. Before you write your program, make it a little easier to write.
