我編程的東西,創建多個教師對象:以這種方式可以使用掃描儀嗎?
public class Teacher {
// 1) Define instance variables
String teacherName;
String catchPhrase;
public static int roomNum;
// 2) Write the constructor method
public Teacher() {
teacherName = "unknown";
catchPhrase = "unknown";
roomNum = 0;
}//end no-arg constructor
public Teacher(String newTeacher, String newCatch, int newRoom) {
teacherName = newTeacher;
catchPhrase = newCatch;
roomNum = newRoom;
}
// 3) Write the proccessing methods (getters and setters)
public void setName(String newName) {
teacherName = newName;
}
public String getName() {
return teacherName;
}
public static int getRoom() {
return roomNum;
}
// 4) Write the out method (eg toString() method)
public String toString() {
String str = "Name: " + teacherName + ". \nCatch phrase: " + catchPhrase + " \nRoom number: " + roomNum + ".";
return str;
}//end toString
public static void main(String args[]) {
}
}
它是這樣執行的:
Teacher teacherName("First Last", "Catch Phrase", 123);
我有多個教師的對象。我試圖讓從用戶輸入檢查掃描儀,看看輸入的號碼是從這些對象中的一個房間號:
while (input != -1) {
Scanner scan = new Scanner(System.in);
input = scan.nextInt();
if(input == Teacher.getRoom()) {
System.out.println("Yes");
} else if(input != Teacher.getRoom()) {
System.out.println("Nope");
}
}
但我不知道該怎麼做。或者如果可能的話。
任何幫助將不勝感激。
謝謝!
編輯:
我嘗試了不同的方式。我試圖使用一個數組與房間號碼,並與輸入進行比較,但它沒有奏效。
int[] rooms = {220, 226, 204, 234, 236, 242, 243, 129, 125, 136, 101, 104, 107, 113, 103, 105, 102, 108, 117, 111, 111, 313, 310, 132, 127, 129, 125,
+ 124, 122, 126, 130, 137, 114, 138, 136, 123, 135, 128, 139, 134, 220, 215, 211, 222, 253, 213, 252, 231, 255, 224, 254,
+ 218, 235, 233, 000, 212, 223, 257, 217, 259, 214, 240, 258, 221, 210, 219, 256, 216, 110, 133, 115, 423, 253, 230, 115, 106, 1062, 418, 415};
if (rooms.equals(input)) {
System.out.println("Yes");
} else {
System.out.println("Nope");
}
這沒有奏效。也沒有:
if (Arrays.asList(rooms).contains(input)) {
System.out.println("Yes");
} else {
System.out.println("Nope");
}
任何幫助獲得這與整數數組,(或更好的方法)的工作,將不勝感激。
謝謝。
EDIT2:
我得到它的工作是這樣的:
if (rooms.contains(input)){
System.out.println("That teacher is in our database!");
//System.out.println(new int[(rooms).indexOf(1)]);
} else {
System.out.println("Sorry, that teachner was not found in our database!");
}
非常感謝您!
'roomNum'不應是靜態的!靜態意味着所有教師共享一個房間號碼。你希望每位老師都有自己的房間號碼。 – 2014-09-26 05:31:11
