i did basic install of oracle xe on linux computer , following java code insert , return data:

try {             //step1 load driver class             class.forname("oracle.jdbc.driver.oracledriver");              //step2 create  connection object             connection con = drivermanager.getconnection(                     "jdbc:oracle:thin:@localhost:1521:xe", "system", "xxx");              //step3 create statement object             statement stmt = con.createstatement();              //step4 execute query             boolean ret = stmt.execute("insert emp values (1, \'john\', 43)");              resultset rs = stmt.executequery("select * emp");             while (rs.next())                 system.out.println(rs.getint(1) + "  " + rs.getstring(2) + "  " + rs.getstring(3));              //step5 close connection object             con.close(); 

but if try use intellij idea database browser dont see xe dabase or table.. using same connect data.

here see on screen

can please tell me should looking table , data.. thanks

there 1 oracle xe database per machine. within single database, you'll have number of schemas. many of schemas installed default (i.e. sys, system, etc.). if coming different database product, mysql or sql server calls "database" similar oracle calls "schema".

based on java code posted, appears created emp table in system schema. bad idea-- should never create new objects in sys or system schema. should creating new schema hold new objects want create. in intellij, appears should able go system schema find table , data inserted. but, again, shouldn't creating objects in system schema in first place.
