我在嘗試將用戶輸入保存到變量中,然後再訪問該變量的內容時遇到了一些麻煩。基本上,用戶輸入關於歌曲的詳細信息,然後將其保存在下一個可用歌曲插槽中(總共4個插槽)。但是當我檢查插槽是空的還是空的時候,由於最後的歌曲細節沒有保存,它總是空的。變量內容不是持久的
代碼:
SongDatabase類:
if (song1.getFileSize() == 0) {
System.out.println("Name of song:");
song1.setName(console.next());
System.out.println("Artist:");
song1.setArtist(console.next());
System.out.println("File size (MB):");
song1.setFileSize(console.nextInt());
System.out.println("Duration (seconds):");
song1.setDuration(console.nextInt());
}
else if (song2.getFileSize() == 0) {
System.out.println("Name of song:");
song2.setName(console.next());
System.out.println("Artist:");
song2.setArtist(console.next());
System.out.println("File size (MB):");
song2.setFileSize(console.nextInt());
System.out.println("Duration (seconds):");
song2.setDuration(console.nextInt());
}
else if (song3.getFileSize() == 0) {
System.out.println("Name of song:");
song3.setName(console.next());
System.out.println("Artist:");
song3.setArtist(console.next());
System.out.println("File size (MB):");
song3.setFileSize(console.nextInt());
System.out.println("Duration (seconds):");
song3.setDuration(console.nextInt());
}
else if (song4.getFileSize() == 0) {
System.out.println("Name of song:");
song4.setName(console.next());
System.out.println("Artist:");
song4.setArtist(console.next());
System.out.println("File size (MB):");
song4.setFileSize(console.nextInt());
System.out.println("Duration (seconds):");
song4.setDuration(console.nextInt());
}
else {
System.out.println("The database is currently full. Please delete a song before adding a new one.");
}
宋類:
public void setName(String inputName) {
name = inputName;
}
public String getName() {
return name;
}
public void setArtist(String inputArtist) {
artist = inputArtist;
}
public String getArtist() {
return artist;
}
public void setFileSize(int inputFileSize) {
fileSize = inputFileSize;
}
public int getFileSize() {
return fileSize;
}
public void setDuration(int inputDuration) {
duration = inputDuration;
}
public int getDuration() {
return duration;
}
我需要在get/set方法添加另一個參數或我在做一些完全錯誤的?任何幫助將不勝感激,謝謝!
你已經離開了字段的聲明等等,以及(據說)顯示「插槽」是「完全空的」的代碼。 –
