Question

我创建了一种方法来检查所有团队中的所有团队，并看到胜率最高的人。一旦循环找到了最高的获胜率，它应该以该胜率回归球队。当我在main方法中调用一行简单的代码时，

System.out.println("The team with the highest winning percentage is: " +highest(tm));

我收到一个编译错误，说它无法找到最高的方法。它的静态因此它可以与团队数组的主要方法进行通信。如果我不理解某事，请向我解释我的误解。

public class teams{
    public static void main(String [] argv){
        /*Team team1 = new Team("knicks");
        Team team2 = new Team("nets");
        team1.play(team2);
        team1.play(team2);
        team2.play(team1);
        team2.printrecord();
        team1.printrecord();
        team2.winpercent();*/
        String[] teamnames = {"knicks", "nets", "lakers", "celtics", "heat", "spurs"};
        Team[] tm = new Team[teamnames.length]; // creates an array of teams

        for (int i=0;i<teamnames.length;i++){       // assigns a team to each string in teamnames
            tm[i] = new Team(teamnames[i]);
        }//for

        for (int i=0;i<teamnames.length;i++){       //nested for loop to have each team play another team once
            for(int k=i+1; k<teamnames.length;k++){
                if(k!=i)
                    tm[i].play(tm[k]);
            }//nestedfor
        }//for

        System.out.println("The team with the highest winning percent is: " +highest(tm));

    }//main
}//teams

class Team{
    double wins; 
    double losses;
    double winningpercent;
    String name;

    public Team(String n){
        name = n;
        wins = 0;
        losses = 0;
        winningpercent = 0;
    }//constructor

    public void lose(){
        losses++;
    }//losses

    public void win(){
        wins++;
    }//wins

    public void printrecord(){
        System.out.println("The W-L record for the " +name+ " is: " +String.format("%d",(long)wins)+"-"+String.format("%d",(long)losses));
    }

    public void play(Team j){
        if((Math.random())<0.5){
            System.out.println("The "+j.name+" Have Won!");
            j.win();
            this.lose();
        }//if
        else {
            System.out.println("The "+name+" Have Won!");
            this.win();
            j.lose();
        }//else
    }//play

    public double winpercent(){
        double winningpercentage = (wins/(losses+wins))* 100;
        System.out.println("The Winning percentage for the " +name+" is: " +winningpercentage+"%");
        this.winningpercent = winningpercentage;
        return winningpercentage;
    }//winningpercent

    public static String highest(Team[] tm){
        String highest = "";
        for (int i=0;i<tm.length;i++){
            for(int k=i+1;k<tm.length;k++){
                if (k!=i && tm[i].winningpercent > tm[k].winningpercent)
                    highest = tm[i].name;
            }//nestedforloop
        }//forloop
        return highest;
    }//highest  

}//Team

Answer 1

是。首先，该方法不是静态的。所以，这个

public String highest(Team[] tm){

应该是

public static String highest(Team[] tm){

然后你需要使用类名（或import static方法） -

System.out.println("The team with the highest winning percent is: " +
    Team.highest(tm));

在main方法java中调用时找不到方法
