Table :FindRows Iteration Error

in Programming Questions • 4 months ago

Hi I'm planning to use the Table Class for an Assignment using a csv file

but I've found that using FindRows or MatchRows gives me

"can only iterate over an instance of java.lang.iterable " error

At the moment even the example code given doesn't work it gives the same error
I'm using processing 2.0b8.

Is the table class still buggy?

Here is the example code taken from processing.org

Table table; void setup() { table = new Table(); table.addColumn("name"); table.addColumn("type"); TableRow newRow = table.addRow(); newRow.setString("name", "Lion"); newRow.setString("type", "Mammal"); newRow = table.addRow(); newRow.setString("name", "Snake"); newRow.setString("type", "Reptile"); newRow = table.addRow(); newRow.setString("name", "Mosquito"); newRow.setString("type", "Insect"); newRow = table.addRow(); newRow.setString("name", "Lizard"); newRow.setString("type", "Reptile"); for (TableRow row : table.findRows("Reptile", "type")) { println(row.getString("name") + ": " + row.getString("type")); } }

After re-organized your mal-formed code post; it just worked:

And didn't you know that stable Processing 2 was released a week ago?

Why are still you on beta 8?

final Table table = new Table();

void setup() {
  table.addColumn("name");
  table.addColumn("type");

  TableRow newRow = table.addRow();
  newRow.setString("name", "Lion");
  newRow.setString("type", "Mammal");

  newRow = table.addRow();
  newRow.setString("name", "Snake");
  newRow.setString("type", "Reptile");

  newRow = table.addRow();
  newRow.setString("name", "Mosquito");
  newRow.setString("type", "Insect");

  newRow = table.addRow();
  newRow.setString("name", "Lizard");
  newRow.setString("type", "Reptile");

  for ( TableRow row: table.findRows("Reptile", "type") )
    println(row.getString("name") + ": " + row.getString("type"));

  exit();
}
