问题 I am a novice Java programmer trying to use classes defined in a different file. So, I've written these two .java files: First, there's MyLibrary.java: package mymainprogram; public class MyLibrary { public class MyRecord { int number; char letter; } public static int TriplePlusThree(int input_number) { return ((input_number*3) + 3); } } Then, MyMainProgram.java: package mymainprogram; import java.util.Scanner; public class MyMainProgram { public static void main(String[] args) { Scanner

问题 Im trying to do a card game (user vs pc) where the first to get 7.5 points win. For that I created a deck that have 4 suits with 10 cards each one. The cards go from 1 to 10, and the value of the cards 1-7 they value the number they have. Cards 8,9 and 10 value 0.5 points. I created an array to store the cards and another to mark a card as deleted when chosen int deck[40] = {1,1,1,1,2,2,2,2,3,3,3,3,4,4,4,4,5,5,5,5,6,6,6,6,7,7,7,7,8,8,8,8,9,9,9,9,10,10,10,10}; int draw[40] = {0}; //array to

问题 I have to reverse two arrays so that, they both have the same values but different references. Here is my code so far. But how to achieve that when both arrays are pointing to the same program arguments? And why does String[] reference reverse the String[] values instead of reversing the program arguments? For example. If the program arguments were 1 2 3 4 5 : String[] values = 5 4 3 2 1 String[] reference = 1 2 3 4 5 public static void main(String[] args) { String[] values = changeValues
