ArrayLists中每個團隊的屬性

Question

所以我有一個包含“比賽信息”的類。 我有一個采用團隊名稱的arraylist。 我只需要一個想法或功能，就可以讓我從其他類（機器人，TeamInfo）中加載信息到ArrayLists中的每個已分配成員中。

同樣，任何能夠改善我的編碼的批評都可以被接受和贊賞。

測試是最主要的。 錦標賽是包含錦標賽信息的類。

package test;
import java.util.Scanner;

/**
 *
 * @author
 */
public class Test {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        String TheTournamentName, Date, Location;
        int SoftwareStations , HardwareStations , FieldTesting;
        Tournament UsingTheMain = new Tournament();
        System.out.printf("Please Enter The Tournament Name\n");
        TheTournamentName = input.nextLine();
        UsingTheMain.setName(TheTournamentName);
        //System.out.printf(UsingTheMain.getName());
        System.out.printf("Please Enter the Date\n");
        Date = input.nextLine();
        UsingTheMain.setDate(Date);
        System.out.printf("Please Enter The Location\n");
        Location = input.nextLine();
        UsingTheMain.setLocation(Location);
        System.out.printf("Please Enter Number of Software Stations you want. Max Allowed is 2\n");
        SoftwareStations = input.nextInt();
        UsingTheMain.setSoftwareStations(SoftwareStations);
        System.out.printf("Please Enter Number of Hardware Stations you want. Max allowed is 2\n");
        HardwareStations = input.nextInt();
        UsingTheMain.setHardwareStations(HardwareStations);
        System.out.printf("Please Enter Number of Field Stations. Max Allowed is 2\n");
        FieldTesting = input.nextInt();
        UsingTheMain.setFieldTesting(FieldTesting);
        System.out.printf("Please Enter 8 Teams");





        // TODO code application logic here
    }

}

Answer 1

您的代碼可能還有其他問題，但是這段代碼肯定是其中之一

public void setTeamNames(int X) {
    for (int i = 0; i >= X; i++)
    {
        int Q = 0;
        String C;
        System.out.printf("Please Enter the %n Team Names ;\n",Q);
        C = input.nextLine();
        TeamNames.add(C);
        Q=1+Q;
    }
}

除非X為負或為空，否則永遠不會滿足要進入循環的條件。 但是，如果x為負或null，我們將進入循環，但永遠不會出現。 我非常懷疑您是否正在嘗試這種行為。

就像@JB Nizet提到的那樣，您應該尊重一些Java編碼約定。 例如變量局部變量和參數命名，以使您的代碼易於閱讀（請為此編輯）。 對本地變量類實例變量和參數名稱使用camelCase約定

示例：建議編寫public void setSoftwareStations(int softwareStations)代替public void setSoftwareStations(int SoftwareStations) public void setSoftwareStations(int softwareStations)
