我目前正在研究一个项目，在该项目中读取包含Pokemon列表以及其特征的CSV文件。我试图运行一个战斗模拟器，随机将这些宠物小精灵相互配对，并比较他们的战斗分数，这是使用他们的特性如速度，攻击力，防御等简单计算的结果。我读了所有的口袋妖怪从CSV文件转换为Pokemon类型的ArrayList。现在，我想随机配对并比较他们的战斗评分;谁拥有更高的分数移动到下一轮，失败者被放入另一个失败的宠物小精灵ArrayList。但是，我不知道如何随机配对宠物小精灵。这里是我的主类的代码至今：如何将ArrayList的随机指数相互配对
import java.io.*;
import java.util.ArrayList;
import java.util.Random;
public class assign1 {
public static void main(String[] args) throws IOException {
String csvFile = args[0]; //path to CSV file
String writeFile = args[1]; //name of output file that contains list of Pokemon and their traits
BufferedReader br = null;
String line = "";
String cvsSplitBy = ",";
ArrayList<Pokemon> population = new ArrayList<Pokemon>();
FileWriter fileWriter = new FileWriter(writeFile);
BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);
try {
br = new BufferedReader(new FileReader(csvFile));
String headerLine = br.readLine(); // used to read first line of CSV file that contains headers
while ((line = br.readLine()) != null) {
Pokemon creature = new Pokemon();
// use comma as separator
String[] pokemon = line.split(cvsSplitBy);
creature.setId(pokemon[0]);
creature.setName(pokemon[1]);
creature.setType1(pokemon[2]);
creature.setType2(pokemon[3]);
creature.setTotal(pokemon[4]);
creature.setHp(Integer.parseInt(pokemon[5]));
creature.setAttack(Integer.parseInt(pokemon[6]));
creature.setDefense(Integer.parseInt(pokemon[7]));
creature.setSpAtk(Integer.parseInt(pokemon[8]));
creature.setSpDef(Integer.parseInt(pokemon[9]));
creature.setSpeed(Integer.parseInt(pokemon[10]));
creature.setGeneration(Integer.parseInt(pokemon[11]));
creature.setLegendary(Boolean.parseBoolean(pokemon[12]));
creature.getCombatScore();
// Adds individual Pokemon to the population ArrayList
population.add(creature);
// Writes to pokemon.txt the list of creatures
bufferedWriter.write(creature.getId() + ". "
+ "Name: " + creature.getName() + ": "
+ "Type 1: " + creature.getType1() + ", "
+ "Type 2: " + creature.getType2() + ", "
+ "Total: " + creature.getTotal() + ", "
+ "HP: " + creature.getHp() + ", "
+ "Attack: " + creature.getAttack() + ", "
+ "Defense: " + creature.getDefense() + ", "
+ "Special Attack: " + creature.getSpAtk() + ", "
+ "Special Defense: " + creature.getSpDef() + ", "
+ "Speed: " + creature.getSpeed() + ", "
+ "Generation: " + creature.getGeneration() + ", "
+ "Legendary? " + creature.isLegendary() + ", "
+ "Score: " + creature.getCombatScore());
bufferedWriter.newLine();
}
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
finally {
if (br != null) {
try {
br.close();
}
catch (IOException e) {
e.printStackTrace();
}
}
}
bufferedWriter.close();
}
}
，这里是我的宠物小精灵类的代码：
public class Pokemon {
String id;
String name;
String type1;
String type2;
String total;
int hp;
int attack;
int defense;
int spAtk;
int spDef;
int speed;
int generation;
boolean legendary;
public Pokemon() {}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getType1() {
return type1;
}
public void setType1(String type1) {
this.type1 = type1;
}
public String getType2() {
return type2;
}
public void setType2(String type2) {
this.type2 = type2;
}
public String getTotal() {
return total;
}
public void setTotal(String total) {
this.total = total;
}
public int getHp() {
return hp;
}
public void setHp(int hp) {
this.hp = hp;
}
public int getAttack() {
return attack;
}
public void setAttack(int attack) {
this.attack = attack;
}
public int getDefense() {
return defense;
}
public void setDefense(int defense) {
this.defense = defense;
}
public int getSpAtk() {
return spAtk;
}
public void setSpAtk(int spAtk) {
this.spAtk = spAtk;
}
public int getSpDef() {
return spDef;
}
public void setSpDef(int spDef) {
this.spDef = spDef;
}
public int getSpeed() {
return speed;
}
public void setSpeed(int speed) {
this.speed = speed;
}
public int getGeneration() {
return generation;
}
public void setGeneration(int generation) {
this.generation = generation;
}
public boolean isLegendary() {
return legendary;
}
public void setLegendary(boolean legendary) {
this.legendary = legendary;
}
public int getCombatScore() {
return (speed/2) * (attack + (spAtk/2)) + (defense + (spDef/2));
}
@Override
public String toString() {
return "Name: " + this.getName()
+ ", Type 1: " + this.getType1()
+ ", Type 2: " + this.getType2()
+ ", Total: " + this.getTotal()
+ ", HP: " + this.getHp()
+ ", Attack: " + this.getAttack()
+ ", Defense: " + this.getDefense()
+ ", Sp. Attack: " + this.getSpAtk()
+ ", Sp. Defense: " + this.getSpDef()
+ ", Generation: " + this.getGeneration()
+ ", Legnedary: " + this.isLegendary()
+ ", Score: " + this.getCombatScore();
}
}
我只希望他们combatScore值相互比较。任何帮助/建议将不胜感激。
这让我走上了正轨。感谢您的建议！ –
