局部变量初始化的问题

Question

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);   
}

提示说的是局部变量TABLE_LOCATIONLABLES可能没有被初始化?可是我初始化了的呀，这个错误如何发生的呢?

Answer 1

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

等号两各有一个，而且String TABLE_LOCATIONLABLES这个还是新定义的，计算机迷糊了，它不认为你上面已经定义了
