### Question:
DataType { public static @Nullable String nameForOid(int oid) { return dataTypes.get(oid); } private  DataType(); static @Nullable String nameForOid(int oid); static int normalizeOid(int oid); static int arrayComponentOid(int oid); static final int UNSPECIFIED; static final int BIT; static final int BIT_ARRAY; static final int BOOL; static final int BOOL_ARRAY; static final int BOX; static final int BOX_ARRAY; static final int BPCHAR; static final int BPCHAR_ARRAY; static final int BYTEA; static final int BYTEA_ARRAY; static final int CHAR; static final int CHAR_ARRAY; static final int CIDR; static final int CIDR_ARRAY; static final int CIRCLE; static final int CIRCLE_ARRAY; static final int DATE; static final int DATE_ARRAY; static final int FLOAT4; static final int FLOAT4_ARRAY; static final int FLOAT8; static final int FLOAT8_ARRAY; static final int INET; static final int INET_ARRAY; static final int INT2; static final int INT2_ARRAY; static final int INT4; static final int INT4_ARRAY; static final int INT8; static final int INT8_ARRAY; static final int INTERVAL; static final int INTERVAL_ARRAY; static final int JSON; static final int JSON_ARRAY; static final int JSONB; static final int JSONB_ARRAY; static final int LINE; static final int LINE_ARRAY; static final int LSEG; static final int LSEG_ARRAY; static final int MACADDR; static final int MACADDR_ARRAY; static final int MACADDR8; static final int MACADDR8_ARRAY; static final int MONEY; static final int MONEY_ARRAY; static final int NAME; static final int NAME_ARRAY; static final int NUMERIC; static final int NUMERIC_ARRAY; static final int OID; static final int OID_ARRAY; static final int PATH; static final int PATH_ARRAY; static final int POINT; static final int POINT_ARRAY; static final int POLYGON; static final int POLYGON_ARRAY; static final int REF_CURSOR; static final int REF_CURSOR_ARRAY; static final int TEXT; static final int TEXT_ARRAY; static final int TIME; static final int TIME_ARRAY; static final int TIMESTAMP; static final int TIMESTAMP_ARRAY; static final int TIMESTAMPTZ; static final int TIMESTAMPTZ_ARRAY; static final int TIMETZ; static final int TIMETZ_ARRAY; static final int UUID; static final int UUID_ARRAY; static final int VARBIT; static final int VARBIT_ARRAY; static final int VARCHAR; static final int VARCHAR_ARRAY; static final int VOID; static final int XML; static final int XML_ARRAY; }### Answer:
@Test public void testNameForOid() throws Exception { for (Field oidField : oidFields) Assert.assertEquals(oidField.getName(), DataType.nameForOid((int) oidField.get(null))); }
