java-局部變量初始化的問題

局部變量初始化的問題

public class DatabaseHandler extends SQLiteOpenHelper {
// All Static variables
// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "contextsManager";
// Locations table name
private static final String TABLE_LOCATIONLABLES = "locationLables";
// LOCATIONLABLES Table Columns names
private static final String KEY_LOCID = "loc_id";
private static final String KEY_LOCNAME = "loc_name";
public DatabaseHandler(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
// Creating Tables
@Override
public void onCreate(SQLiteDatabase db) {
    String TABLE_LOCATIONLABLES = "CREATE TABLE " + TABLE_LOCATIONLABLES + "("
            + KEY_LOCID + " INTEGER PRIMARY KEY," + KEY_LOCNAME + " TEXT,"
            +  ")";
    db.execSQL(TABLE_LOCATIONLABLES);   
}

提示說的是局部變量TABLE_LOCATIONLABLES可能沒有被初始化?可是我初始化了的呀，這個錯誤如何發生的呢?

最佳回答：

String TABLE_LOCATIONLABLES = "CREATE TABLE " + TABLE_LOCATIONLABLES + "("

等號兩各有一個，而且String TABLE_LOCATIONLABLES這個還是新定義的，計算機迷糊了，它不認為你上面已經定義了
