java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist error message in netbeans 8.0.1 - sql

Question

when i was trying to delete all records form Oracle database using the following code i got this exception,
QUERYY:: delete from DMUSER.CAMERA_DATA1
java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist
Actually here I wanted to create a data mining application using oracle SQL developer and the netbeans IDE. So my workflow is looks like as follow in oracle SQL developer,
The code part that I have used to delete a record from database as follows,
public void deleteData()throws SQLException {
Statement stmt = null;
String query = "delete from DMUSER.CAMERA_DATA1";
System.out.println("QUERYY:: " + query);
try {
stmt = getConnection().createStatement();
int rs = stmt.executeUpdate(query);
if (rs > 0) {
System.out.println("<-------------------Record Deleted--------------->");
}
} catch (SQLException e) {
e.printStackTrace();
} finally {
if (stmt != null) {
stmt.close();
}
}
}
I'm very new to the environment and searched many related questions even in stack but couldn't find exact answer which makes my work successful. Please help me to solve this.

QUERYY:: delete from DMUSER.CAMERA_DATA1
java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not
exist
You need to check, if CAMERA_DATA1 table/view exists in DMUSER schema or not.
Try connecting to same database and schema and check, if table exist or not. If not, then you need to create this table/view in same schema.
Referring to your screenshot provided, I can see CAMERA_DATA table instead of CAMERA_DATA1. So, you can either correct the SQL query to below
String query = "delete from DMUSER.CAMERA_DATA";
