) Experimental summary1. Complete the scoring system with object-oriented thinkingProgram Design ideas: Enter the number of contestants, the number of judges, and then enter the player information, so that all the judges to score the contestants, after the score will be sorted, remove the highest score and the lowest score, the average score, will be the final average spread to the player's information, as the final result of the contestant;Problem:Workaround:2.Email VerificationThis question is

character of each file is intercepted by the method of the string class, and then the upper method is used to complete the case conversion of the character, plus the first string followed by a re-assignment to the file name. In the loop, press the filename string "." Take apart, save the last array element after the break, define an array of counts after the loop, the size equals the array of file types, and from the first query there is no element with the same, the corresponding count array +

Java's current heat has declined, but there are still a lot of people who learn java. Java's post is also a lot of infiltration. So, those classic Java knowledge points, you can see the problem can say 123? Come and have a look.The difference between 1.JDK and JRE What is the difference between 2.final, finally, and finalize?3. The difference between threads and processesHow does the HashMap in 4.

executed, the original constructors, the overloaded constructors, and the subclasses of the same kind.Think question 7:Only static data is allowed to be accessed in a static method. So how do you access an instance member of a class in a static method (that is, a field or method that has no static keyword attached)?The specific code for accessing instance members by parameters is as follows:public class Test2 {public static void Main (string[] args){Test t=new test ();int A=t.getyear ();T.INPUT
