获取字符串中第一个字符的unicode值

Getting the unicode value of the first character in a string

我基本上被要求获取字符串的 Unicode 值,将其乘以 10%,然后加上对象当前的任何级别。令人沮丧的是,事实证明我已将逻辑包括代码在内,但我仍然收到一条错误消息:expected:<0> but was:<8>。任何建议,也许这只是我必须在逻辑上做出的细微差别,尽管我相当确定它是正确的。 注意 getLevel 方法,因为这是错误所在

public class PouchCreature implements Battleable {

private String name;
private int strength;
private int levelUps;
private int victoriesSinceLevelUp;

/**
 * Standard constructor.  levelUps and victoriesSinceLevelUp start at 0.
 * 
 * @param nameIn desired name for this PouchCreature
 * @param strengthIn starting strength for this PouchCreature
 */
public PouchCreature(String nameIn, int strengthIn) {
    this.name = nameIn;
    this.strength = strengthIn;
    this.levelUps = 0;
    this.victoriesSinceLevelUp = 0;
}


/**
 * Copy constructor.  
 * 
 * @param other reference to the existing object which is the basis of the new one
 */
public PouchCreature(PouchCreature other) {
    this.name=other.name;
    this.strength=other.strength;
    this.levelUps=other.levelUps;
    this.victoriesSinceLevelUp=other.victoriesSinceLevelUp;
}


/**
 * Getter for skill level of the PouchCreature, which is based on the
 * first character of its name and the number of levelUps it has.
 * Specifically, the UNICODE value of the first character in its name
 * taken %10 plus the levelUps.
 * 
 * @return skill level of the PouchCreature
 */
public int getLevel() {
    int value = (int)((int)(getName().charAt(0)) * 0.1);
    return value + this.levelUps;
}

您说过您应该增加 10% 的价值。不过,您实际上在做的是 减少 90%,只取其中的 10%(然后将其截断为 int)。 67.0 * 0.1 = 6.7,截断为 int 时为 6

0.1 更改为 1.1 增加 10%:

int value = (int)((int)(getName().charAt(0)) * 1.1);
// --------------------------------------------^

在那里,如果 getName() returns "Centaur"(例如),C 具有 Unicode 值 67,并且 value最终成为 73.

我们需要查看您调用 class 时使用的代码,它会生成您的错误消息。为什么期望为 0?根据您提供的信息,8 似乎是一个有效的 return 值。
