问题 I'm looking to keep the following menu repeating: Choose an Option 1 - FIND 2 - IN-SHUFFLE 3 - OUT-SHUFFLE So that when a user selects an option (and this will be executed), afterwards they can select other options as well. Problem: My code keeps the menu repeating without stopping. import java.util.Scanner; public class MainMenu { public static void main(String[] args) { int userChoice; userChoice = menu(); } private static int menu() { Scanner scanner = new Scanner(System.in); System.out

问题 I have a collection of strings. For example, string[] coll={"1", "2", "3" ..."100"..."150"...} and I have respective methods for the string collection such as void Method1, void Method2, void Method100 I select appropriate method like that: string selector=string.Empty; switch(selector) { case "1": MethodOne(); break; ........ case "150": Method150(); break; } The above code is really bored and I will have more string elements in the string collection {"150" ...

问题 I have a homework assignment where the program will accept any phone number in the format similar to 555-GET-FOOD. The task is to map the alphabetic letters to numbers and translate the number to its numeric equivalent. For example: A, B, C = 2; D, E, F = 3; etc... We have not covered Classes or creating maps at this point so these would not be viable solutions. This chapter does cover the enum so I am working to solve using an Enumerated type. I have a method set up to validate the data

问题 My Class is looking like this: public class Month { private int numOfMonth; private int monthNum; public int monthNum() { return monthNum = 1; } public void setMonthNum(int monthNum){ switch (monthNum) { case 1: System.out.println("January"); break; case 2: System.out.println("February");break; case 3: System.out.println("March");break; case 4: System.out.println("April");break; case 5: System.out.println("May");break; case 6: System.out.println("June");break; case 7: System.out.println("July

问题 I'm building a login style application within android studio. As part of this I have created a rule that if the counter which monitors the number of invalid login attempts, gets to 0. I've currently got it that when the counter gets to 0, the login button is disabled. I was wondering if there is any way of disabling this button for a set period of time, rather than for infinity? switch (counter) { case 0: b1.setEnabled(false); break; case 1: tx1.setBackgroundColor(Color.RED); break; case 2:

问题 We have a subfolder that is a relative svn external (../project/subfolder). In a fresh trunk checkout it points to (...TRUNK/project/subfolder) and in a fresh branch checkout it points to (...BRANCH/branchName/project/subfolder). But if you do a switch on the project containing the subfolder, the subfolder stays pointing at TRUNK. Alternately if you do a BRANCH checkout and switch to TRUNK it stays pointing at BRANCH. Shouldn't an svn:switch update relative externals? Is there some sort of

问题 I'm making a short quiz in PHP that tells you what creature your thinking of based on 4 yes/no questions. I have made it so that depending on your answer to each question you get taken to a different question, I did this using mainly switch statements. My question is is there any way that I can make a switch statement with the condition as the id from the submit buttons from the form? echo "<form method ='post' action='Creatures.php'> <input type='submit' name='answer' id='1' value='Yes' />

问题 I am building my custom UIControl, a custom button built as an IBDesignable, which needs to change based on the size class in which it is being displayed. I have a method -setupForTraitCollection, which looks like this: func setupForTraitCollection() { switch(traitCollection.horizontalSizeClass, traitCollection.verticalSizeClass) { case (.Regular, _): // iPad - not compressed design compressed = false default: // iPhone - compressed design compressed = true } } This code works great when

问题 I am working on a rock paper scissors program, but this time the computer chooses rock half the time, scissors a third of the time, and paper only one sixth of the time. The way I did this was I enumerated six possible computer choice values: enum choicec {rock1, rock2, rock3, scissors1, scissors2, paper}; choicec computer; But then, after the computer makes its choice, I have to convert these enumerated values to either rock, paper, or scissors. I did this using a switch-case statement:
