java resultset
Hi there
I have a strange problem with my Java app.
I'm testing if username and password is correct and retrieve 1 or 0.
But when I test with if (a == "1") then I get negative response as if the value stored in 'a' doesn't match.
I debugged the application but debugger shows a = "1" so I'm completely stupefied by this.
Please help.
===============================================
Statement select = c.createStatement();
ResultSet result = select.executeQuery("select count(*) from system_user where nm = '"
+ username + "' and pwd = '" + password + "'");
if (result != null) {
System.out.println("result !null");
while (result.next()) {
a = result.getString(1);
System.out.println(a);
if (a == "1"){
System.out.println(result.getString(1) + "Access granted");
}
}
}
if (a == "1"){
System.out.println("Access granted !!!");
}else{
System.out.println("User " + username + " does not exists in the databse!!!");
}
result.close();
