You have to first create the variable, eg:
NetcdfFileWriteable ncfle = new NetcdfFileWriteable(); // from netHead
ncfle.setName(outfle); // output file name
// define dimensions
Dimension netOut_nStrings = ncfile.addDimension("netOut_nStrings", 2);
Dimension netOut_strLen = ncfile.addDimension("netOut_strLen", 10);
// define Variable "netOut"
Dimension[] dims = new Dimension[2];
dims[0] = netOut_nStrings ;
dims[1] = netOut_strLen ;
ncfile.addVariable("netOut", char.class, dims);
try {
ncfle.create(); // create CDF binary file
} catch (IOException e) { System.out.println("ERROR creating file"); }
if you look at the user manual, it has some complete examples
