我不明白為什么我的編譯器找不到類，考慮到我不是已經(jīng)在我的方法中做到了嗎？編譯器指向以下行：Weightpublic boolean checkWeight`Weight first = new Weight();`和`Weight second = new Weight();`public class Guard { int stashWeight; public Guard ( int maxWeight ) { this.stashWeight = maxWeight; } public boolean checkWeight (Weight maxWeight) { if ( maxWeight.weight >= stashWeight ) { return true; } else { return false; } } public static void main (String[] args ) { Weight first = new Weight(); first.weight = 3000; Weight second = new Weight(); second.weight = 120; Guard grams = new Guard(450); System.out.println("Officer, can I come in?"); boolean canFirstManGo = grams.checkWeight(first); System.out.println(canFirstManGo); System.out.println(); System.out.println("Officer, how about me?"); boolean canSecondManGo = grams.checkWeight(second); System.out.println(canSecondManGo); }}

方法參數(shù)“maxWeight”的類型為“Weight”，Java無法找到解析程序依賴關(guān)系的定義。未能通過類路徑找到類將導(dǎo)致錯誤“找不到符號”。您可能希望定義類“Weight”并將其導(dǎo)入，就像其他人對您所做的那樣。
你真的需要“重量”類嗎？您只是將通過的論點與“警衛(wèi)”的stashWeight進(jìn)行比較。
您的公共方法可以簡單地是：
public boolean checkWeight(int maxWeight) {
return maxWeight >= stashWeight;
}
主方法可以更新為：
public static void main(String[] args) {
int firstWeight = 3000;
int secondWeight = 120;
Guard grams = new Guard(450);
System.out.println("Officer, can I come in?");
boolean canFirstManGo = grams.checkWeight(firstWeight);
System.out.println(canFirstManGo);
System.out.println();
System.out.println("Officer, how about me?");
boolean canSecondManGo = grams.checkWeight(secondWeight);
System.out.println(canSecondManGo);
}

您的代碼中缺少權(quán)重類 請參閱以下代碼
class Weight {
public int weight;
public int getWeight() {
return weight;
}
public void setWeight(int weight) {
this.weight = weight;
}
}
public class Guard {
int stashWeight;
public Guard(int maxWeight) {
this.stashWeight = maxWeight;
}
public boolean checkWeight(Weight maxWeight) {
if (maxWeight.weight >= stashWeight) {
return true;
} else {
return false;
}
}
public static void main(String[] args) {
Weight first = new Weight();
first.weight = 3000;
Weight second = new Weight();
second.weight = 120;
Guard grams = new Guard(450);
System.out.println("Officer, can I come in?");
boolean canFirstManGo = grams.checkWeight(first);
System.out.println(canFirstManGo);
System.out.println();
System.out.println("Officer, how about me?");
boolean canSecondManGo = grams.checkWeight(second);
System.out.println(canSecondManGo);
}
}
輸出
**
Officer, can I come in?
true
Officer, how about me?
false

你應(yīng)該像這樣定義類：Weight
public class Weight {
public int weight;
public int getWeight() {
return weight;
}
public void setWeight(int weight) {
this.weight = weight;
}
}
輸出：
Officer, can I come in?
true
Officer, how about me?
false
或者使用關(guān)鍵字導(dǎo)入您的類。Weightimport
