关于调用function返回ARRAY的问题

[lovedudd]

为什么调用function返回ARRAY，取出来的数据都是16进制数，有什么问题吗

[lovedudd]

CREATE OR REPLACE type emparray IS varray(1000) of varchar2(100)
/
CREATE OR REPLACE FUNCTION getEmpArray
RETURN EMPARRAY AS
l_data EmpArray := EmpArray();
begin
l_data.extend;
l_data(l_data.count) := '111';
RETURN l_data;
END;
/


用java调用的时候

public static void main( ) {..................
OracleCallableStatement stmt =(OracleCallableStatement)conn.prepareCall ( "begin ?:= getEMpArray; end;" );
// The name we use below, EMPARRAY, has to match the name of the
// type defined in the PL/SQL Stored Function
stmt.registerOutParameter( 1, OracleTypes.ARRAY,"EMPARRAY" ); stmt.executeUpdate();
// Get the ARRAY object and print the meta data assosiated with it
ARRAY simpleArray = stmt.getARRAY(1);
System.out.println("Array is of type " + simpleArray.getSQLTypeName()); System.out.println("Array element is of type code "+simpleArray.getBaseType());
System.out.println("Array is of length " + simpleArray.length());
// Print the contents of the array
String[] values = (String[])simpleArray.getArray();
for( int i = 0; i < values.length; i++ )
System.out.println( "row " + i + " = '" + values[i] +"'" );

values[i] 打印出来的就是16进制数了，不知道为什么，
望高人能解决！！！！！！！
谢谢
