我正在制作一个rpg类生成器，它根据用户选择的项传递stat值，根据这个选择，会生成一个新的类示例，但是当我显示值时，就好像从未传递过值一样。
下面是我的代码，首先是类页面，然后是一个用于测试和设置类值的文件：
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);
}
}下面是一个类，它有一个主要的测试方法：
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");
System.out.println(" 11 - ISTJ");
System.out.println(" 12 - ISFJ");
System.out.println(" 13 - ENTP");
System.out.println(" 14 - ENFP");
System.out.println(" 15 - INTJ");
System.out.println(" 16 - INFJ");
int choice = inputDevice.nextInt();
switch(choice)

问题似乎出在
setMinorStats方法。从实现来看，它似乎在计算一些值。但是，这些值没有设置到对象（即没有this.something = value工作分配）。该方法修改了传递的参数的值，但是不会因为java的存在而改变实际值
pass by value. 我建议看一下这些例子。ut6juiuv2#
作为调试时的一般原则，请输入一个默认值，然后查看是否出现该值，这样您就知道您的程序是否根本没有到达开关，或者只是无法识别任何值（如果有）。

问题是，你从来没有真正设置任何属性，你打印（生命力，耐用性等）。
你的意思是在setminorstats（）中设置它们吗？
在setminorstats（）方法的if语句中，添加这样的内容
this.Vitality = Major;如果用下面我的方法替换您的方法，并在第一种情况下使用键盘输入1运行，您将看到vitality在输出时设置为8。sulc1iza4#
这是我的问题的一个解决方案，我简单地将我的方法分为三个其他方法，并使它们具有返回语句，如下所示。
