不是吧！
你看JDK帮助中ResultSet中是这么说的,并没有说该函数是abstract的:
public Array getArray(String colName)
throws SQLException
Retrieves the value of the designated column in the current row of this ResultSet object as an Array object in the Java programming language. Parameters:
colName - the name of the column from which to retrieve the value
Returns:
an Array object representing the SQL ARRAY value in the specified column
Throws:
SQLException - if a database access error occurs
Since:
1.2

查了一下oracle-jdbc的帮助文档:
里面有个 OracleResultSet,提供
ARRAY getARRAY(int columnIndex)
Oracle extension.
这样看来应该是实现了ResultSet接口的getArray()函数!
再说任何实现某接口的类必需要实现interface的所有abstract函数的!
