私は私のコードを実行しています、そしてそれが最初の印刷ステートメントを言った後、それは一時停止します。関数を「挿入」と呼び、何も応答しない時点で一時停止します。「犬、猫、馬を追加」と表示されますが、停止し、その後は何もしません。
主な機能
package assignment2;
public class Main {
public static void main(String[] args) {
OrderedStringList myList = new OrderedStringList(5);
System.out.println("adding dog, cat, & horse");
myList.Insert("dog");
myList.Insert("cat");
myList.Insert("horse");
myList.Display();
System.out.println("Value pig find = "+ myList.Find("pig"));
System.out.println("Value horse find = "+ myList.Find("horse"));
System.out.println("Adding mouse & rat");
myList.Insert("mouse");
myList.Insert("rat");
myList.Display();
System.out.println("myList size: "+ myList.Size());
if (!myList.Insert("chinchilla"))
System.out.println("Could not add chinchilla, full");
System.out.println("Removing dog, adding chinchilla.");
myList.Delete("dog");
myList.Insert("chinchilla");
myList.Display();
}
}
これが私の関数のコードです

boolean result = false;
int index = 0;
if (numUsed < length) {
while (index < numUsed) {
int compare = storage[index].compareTo(value);
if (compare < 0)
index++;
}
moveItemsDown(index);
storage[index] = value;
numUsed++;
result = true;
}
return result;
}
private void moveItemsDown(int start){
int index;

index++;
}

return result;
}

int location;
location = FindIndex(value);
if (location >= 0) {
moveItemsUp(location);
numUsed--;
result = true;
}
return result;
}
public void Display() {

System.out.println("list Contents: ");

}
System.out.println("-------------");
System.out.println();
}

System.out.println();
