OK, thanks, now I understand the question.

Assume you have a ucar.netcdf.Variable ncvar that you got from the
getVariableIterator() method of NetcdfFile, for example.

To get its type, use 

  ncvar.getComponentType()

which returns a Class whose toString() method can be used for the type
string.

To get its dimensions, use a dimension iterator:

  ucar.netcdf.DimensionIterator iter=ncvar.getDimensionIterator();

To get the name for each dimension, use its getName() method:

  iter.next().getName()

This is all done in a private method in the source for
ucar.nc2.Variable:

  private void getFullNameN(StringBuffer buf) {
    buf.append(ncvar.getComponentType());
    buf.append(" ");
    buf.append(ncvar.getName());
    buf.append("(");
    ucar.netcdf.DimensionIterator iter=ncvar.getDimensionIterator();
    while( iter.hasNext()) {
      buf.append( iter.next().getName() );
      if(!iter.hasNext())
        break;
      buf.append(",");
    }
    buf.append(")");
  }
