Question

I got everything working and it prints the right result with header (column name) and value. However I wanted to change a plain and unorganized result into a really nice output table format just like MySql table result with dash lines from query. How do I do that?

Statement statement = conn.createStatement();
ResultSet rs = statement.executeQuery("SELECT * FROM quarter");
ResultSetMetaData rsMetaData = rs.getMetaData();
int numberOfColumns = rsMetaData.getColumnCount();
for(int i = 1; i <= numberOfColumns; i++)
{
    System.out.print(rsMetaData.getColumnLabel(i) + " ");
}
System.out.println();
while (rs.next())
{
    for(int e = 1; e <= rsMetaData.getColumnCount(); e++)
    {
        System.out.print(rs.getString(e) + " ");
    }
    System.out.println();
}

You can use String.format() method with appropriate format string.

For instance,

StringBuilder sb=new StringBuilder();

for(int i = 1; i <= numberOfColumns; i++)
{
    sb.append(String.format("| %-10s",rsMetaData.getColumnLabel(i)));
}
