Using Class Methods

public java.lang.String[] fieldNames()

Input Parameters

None

Example — Getting the Field Names of a Structure Array

Create an MWStructArray object with three fields and display the field names:

int[] sdims = {1, 2};

String[] sfields = {"f1", "f2", "f3"};

MWStructArray S = new MWStructArray(sdims, sfields);

String[] str = S.fieldNames();

System.out.print("The structure has the fields: ");

for (int i=0; i<S.numberOfFields(); i++)

System.out.print(" " + str[i]);

When run, the example displays this output:

The structure has the fields: f1 f2 f3

getDimensions. MWStructArray inherits this method from the MWArray

class.

isEmpty.

MWStructArray inherits this method from the MWArray class.

numberOfDimensions.

MWStructArray inherits this method from the

MWArray class.

numberOfElem ents.

MWStructArray inherits this m ethod from the MWArray

class.

numberOfFields. This method returns the number of fields in this array.

The prototype for the

numberOfFields method is

4-123

1 2 ... 194 195 196 197 198 199 200 201 202 203 204 ... 291 292
