Question

已为我提供了一个对象以及使用该对象的几种方法。我很难打印要分配给变量的字符串。目前，我不确定是否分配所有新值，并且无法打印任何值。以前的迭代仅打印参考。

问题：我要分配新的字符串值吗？如何使用给定的方法打印字符串？

这是我提供的代码

str.sortWith{ case (c1,c2) => c1.compareTo(c2) < 0}
//"      &ADLOOOPSSTacdeeeghiiinoooppprrrsv"

这是我当前的代码

public class Team implements Comparable<Team> {

public String toString(String team, int wins) {
    return team + ": " + wins;
}

// Data fields
private String name;
private int winCount;

Team() {
    name = "Sooners";
    winCount = 1;
}

Team(String inputName) {
    name = inputName;
    winCount = 1;
}

Team(String inputName, int inputWinCount) {
    name = inputName;
    winCount = inputWinCount;
}

// ----------------------------------------------------
// Getters and Setters 
/**
 * @return the name
 */
public String getName() {
    return name;
}

/**
 * @param name
 *            the name to set
 */
public void setName(String name) {
    this.name = name;
}

/**
 * @return the winCount
 */
public int getWinCount() {
    return winCount;
}

/**
 * @param winCount
 *            the winCount to set
 */
public void setWinCount(int winCount) {
    this.winCount = winCount;
}

/**
 * Increments the winCount variable by one for this Team
 */
public void incrementWinCount() {
    winCount++;
}

/**
 * This method allows you to check to see if this Team object has the same
 * name as another Team object.
 * 
 * This method allows you to use the contains method in ArrayList to see
 * if any element in an array list has the same name as a specific Team.
 * 
 * @param o
 *            the other Team being compared to.
 */
@Override
public boolean equals(Object o) {
    return name.equals(((Team) o).name);
}

/**
 * This method allows you to check to see if this Team object has the same
 * name as another Team object
 * 
 * @param otherTeam
 *            one team
 */
public boolean sameName(Team otherTeam) {
    return name.equals(otherTeam.name);
}
/**
 * This method allows you to check to see if this Team object has the same
 * name as another Team object
 * 
 * @param team1
 *            one team
 * @param team2
 *            the other team
 */
public static boolean sameName(Team team1, Team team2) {
    return team1.name.equals(team2.name);
}

/**
 * This method allows you to sort an ArrayList of Team items using
 * Collections.sort
 * 
 * @param o
 *            the other Team being compared to.
 * @return -1 if this Team item should come first, +1 if this Team item
 *         should come after the other, and 0 if this Team item is
 *         equivalent to the other.
 */
@Override
public int compareTo(Team o) {
    if (this.winCount < o.winCount) {
        return -1;
    } else if (this.winCount > o.winCount) {
        return 1;
    }
    return 0;
}

}

他们给你的toString方法的原始代码是什么？是否添加了参数？更好的方法是让对象在方法内部使用其数据字段。在您的for循环中传递成员变量是不必要的，并且只是错误的代码。相反，您想要执行以下操作：

JSON.parse()

在循环中，如果要打印结果，只需执行以下操作：

public String toString() {
    return name + ": " + wins;
}

Array Loop正在打印引用而不是字符串
