我正在制作一个RPG类构建器，它根据用户选择的项目传递stat值，根据该选择创建一个新的类实例，但是当我显示值时，就好像值是从不的过去了。
这是我的代码首先是Class页面，然后是一个要测试的文件并设置Class值：
package com.polaris.mbti;
public class MBTI_Type
{
private int Se;
private int Si;
private int Ne;
private int Ni;
private int Te;
private int Ti;
private int Fe;
private int Fi;
private int Vitality;
private int Durability;
private int Strength;
private int Tact;
private int Loyalty;
private int Friendliness;
private int Ambition;
private int Insight;
private int Foresight;
private int Humanity;
private int Revelation;
private int Charisma;
private int Dexterity;
private int Evasion;
private int Accuracy;
private int Agility;
private int Zest;
private int Grace;
private int Intelligence;
private int Curiousity;
private int Analysis;
private int Idealism;
private int Enthusiasm;
private int Conviction;
public void setBaseStats(int introSen, int extroSen, int introThk, int extroThk, int introInuit, int extroInuit, int introFel, int extroFel)
{
Se = extroSen;
Si = introSen;
Ne = extroInuit;
Ni = introInuit;
Te = extroThk;
Ti = introThk;
Fe = extroFel;
Fi = introFel;
setMajorStats();
}
public void setMajorStats()
{
setMinorStats(Te, Si, Vitality, Durability, Strength);
setMinorStats(Te, Ni, Ambition, Insight, Foresight);
setMinorStats(Fe, Si, Tact, Loyalty, Friendliness);
setMinorStats(Fe, Ni, Humanity, Revelation, Charisma);
setMinorStats(Ti, Se, Dexterity, Evasion, Accuracy);
setMinorStats(Ti, Ne, Intelligence, Curiousity, Analysis);
setMinorStats(Fi, Se, Agility, Zest, Grace);
setMinorStats(Fi, Ne, Idealism, Enthusiasm, Conviction);
}
public void setMinorStats(double A, double B, double Major, double MinorA, double MinorB)
{
Major = (A + B)/2;
if(A > B)
{
MinorA = (Major) - 1;
MinorB = (Major) + 1;
}
if(B > A)
{
MinorA = (Major) + 1;
MinorB = (Major) - 1;
}
}
public void levelUp()
{
}
public void showStats()
{
System.out.println(Vitality);
System.out.println(Durability);
System.out.println(Strength);
System.out.println(Tact);
System.out.println(Loyalty);
System.out.println(Friendliness);
System.out.println(Ambition);
System.out.println(Insight);
System.out.println(Foresight);
System.out.println(Humanity);
System.out.println(Revelation);
System.out.println(Charisma);
System.out.println(Dexterity);
System.out.println(Evasion);
System.out.println(Accuracy);
System.out.println(Agility);
System.out.println(Zest);
System.out.println(Grace);
System.out.println(Intelligence);
System.out.println(Curiousity);
System.out.println(Analysis);
System.out.println(Idealism);
System.out.println(Enthusiasm);
System.out.println(Conviction);
}
}
以下是具有测试主要方法的类：
package com.polaris.mbti;
import java.util.Scanner;
public class TestMBTI2
{
public static void main(String[] args)
{
Scanner inputDevice = new Scanner(System.in);
System.out.println("Please enter a personality type from the choices:");
System.out.println(" 1 - ESTJ");
System.out.println(" 2 - ENTJ");
System.out.println(" 3 - ISTP");
System.out.println(" 4 - INTP");
System.out.println(" 5 - ESFJ");
System.out.println(" 6 - ENFJ");
System.out.println(" 7 - ISFP");
System.out.println(" 8 - INFP");
System.out.println(" 9 - ESTP");
System.out.println(" 10 - ESFP");

答案 0 :(得分：1)
问题似乎与setMinorStats方法有关。从实施来看，它似乎在计算一些价值。但是，这些值未设置为对象（即没有this.something = value分配）。
该方法修改了传递的参数值，但由于Java为pass by value，因此无法更改实际值。我建议您查看these示例。
答案 1 :(得分：0)
作为调试时的一般原则，坚持使用默认值并查看是否出现，然后您就会知道您的程序是否完全没有进入交换机，或者只是没有识别出您拥有的值。
答案 2 :(得分：0)
问题是你从未真正设置过你正在打印的任何属性（活力，耐久性等）。
你的意思是在setMinorStats（）中设置它们吗？
在setMinorStats（）方法的if语句中，为此效果添加一些内容
this.Vitality = Major;
如果你用下面的方法替换你的方法，并且在第一种情况下用键盘输入1运行，你会看到Vitality在输出时设置为8。
public void setMinorStats(double A, double B, double Major, double MinorA, double MinorB)
{
Major = (A + B)/2;
if(A > B)
{
MinorA = (Major) - 1;
MinorB = (Major) + 1;
/*
* Here is what you need to do-- set your fields based on your logic
*/
this.Vitality = (int)Major;
}
if(B > A)
{
MinorA = (Major) + 1;
MinorB = (Major) - 1;
}
}
答案 3 :(得分：0)
这是我的问题的解决方案，我只是将我的方法分成另外三个，并使它们具有返回语句，如下所示。
public void setBaseStats(int introSen, int extroSen, int introThk, int extroThk, int introInuit, int extroInuit, int introFel, int extroFel)
{
Se = extroSen;
Si = introSen;
Ne = extroInuit;
Ni = introInuit;
Te = extroThk;
Ti = introThk;
Fe = extroFel;
Fi = introFel;
setMajorStats();
}
public void setMajorStats()
{
Vitality = setMinorStats(Te, Si);
Durability = setMinorStatsA(Vitality, Te, Si);
Strength = setMinorStatsB(Vitality, Te, Si);
Ambition = setMinorStats(Te, Ni);
Insight = setMinorStatsA(Ambition, Te, Ni);
Foresight = setMinorStatsB(Ambition, Te, Ni);
Tact = setMinorStats(Fe, Si);
Loyalty = setMinorStatsA(Tact, Fe, Si);
Friendliness = setMinorStatsB(Tact, Fe, Si);
Humanity = setMinorStats(Fe, Ni);
Revelation = setMinorStatsA(Humanity, Fe, Ni);
Charisma = setMinorStatsB(Humanity, Fe, Ni);
Dexterity = setMinorStats(Ti, Se);
Evasion = setMinorStatsA(Dexterity, Ti, Se);
Accuracy = setMinorStatsB(Dexterity, Ti, Se);
Intelligence = setMinorStats(Ti, Ne);
Curiousity = setMinorStatsA(Intelligence, Ti, Ne);
Analysis =setMinorStatsB(Intelligence, Ti, Ne);
Agility = setMinorStats(Fi, Se);
Zest = setMinorStatsA(Agility, Fi, Se);
Grace = setMinorStatsB(Agility, Fi, Se);
Idealism = setMinorStats(Fi, Ne);
Enthusiasm = setMinorStatsA(Idealism, Fi, Ne);
Conviction = setMinorStatsB(Idealism, Fi, Ne);
}
public int setMinorStats(int A, int B)
{
int Major = (A + B)/2;
return Major;
}
public int setMinorStatsA(int Major, int A, int B)
{
int MinorA = 0;
if(A > B)
MinorA = (Major) - 1;
if(B > A)
MinorA = (Major) + 1;
return MinorA;
}
public int setMinorStatsB(int Major, int A, int B)
{
int MinorB = 0;
if(A > B)
MinorB = (Major) + 1;
if(B > A)
MinorB = (Major) - 1;
return MinorB;
}
