Unreported exception java.sql.SQLException; must be caught or declared to be thrown? [duplicate]

This question already has an answer here: What does "error: unreported exception <XXX>; must be caught or declared to be thrown" mean and how do I fix it? (1 answer) Closed 7 months ago.

I got this error while trying to compile the below code. I would like to know what is I have done wrong.

unreported exception java.sql.SQLException; must be caught or declared to be thrown
 Class.forName(myDriver);

               ^

private void setupInfo() {

    Driver driver = new org.gjt.mm.mysql.Driver();
    String url = "jdbc:mysql://localhost:3306/test";
    String username = "root";
    String password = "123456";

    String problemFeatureSpecTableName = "ProblemFeatureSpec";
    String solutionFeatureSpectTableName = "SolutionFeatureSpec";
 开发者_StackOverflow   String classTableName = "Class";
    String extraDataTableName = "ExtraData";
    String casebaseTablename = "CaseBase";
    String problemTableName = "Problem";
    String solutionTableName = "Solution";
    String inactiveContextsTableName = "InactiveContext";
    String constantsTableName = "Constants";
    dbInfo = new DBInfo(new JDBCDriverInfo(driverName, url, username, password),constantsTableName);
    problemSpecInfo = new FeatureSpecRDBInfo(problemFeatureSpecTableName, classTableName, extraDataTableName);
    solutionSpecInfo = new FeatureSpecRDBInfo(solutionFeatureSpectTableName, classTableName, extraDataTableName);
    rdbCasebaseInfo = new RDBCaseBaseInfo(casebaseTablename, solutionTableName, problemTableName, inactiveContextsTableName);
}

You either need to catch the exception in your method:

public void setupInfo()
{
    try
    {
        // call methods that might throw SQLException
    }
    catch (SQLException e)
    {
        // do something appropriate with the exception, *at least*:
        e.printStackTrace();
    }
}

Or declare the method to throw SQLException:

private void setupInfo() throws SQLException
{
    // call methods that might throw SQLException
}

Catch the exception or throw it. Better use an IDE (Eclipse or Netbeans), which will tell you the error the moment you press enter.

This line of code throws an uncaught exception:

Driver driver = new org.gjt.mm.mysql.Driver();

try this:

try {
   Driver driver = new org.gjt.mm.mysql.Driver();
}
catch (java.sql.SQLException e) {
  // you may want to do something useful here
 // maybe even throw new RuntimException();
}

Always try to get help from your IDE. IDEs can often fix the error automatically. Press alt+enter in IntelliJ IDEA or ctrl+1 in Eclipse and choose to fix the error.
