increasing the value of the variable that set to DataElement type

[taepy]

if a variable that set to DataElement type, how can we increase the value of that variable?

ex:

DataElement time;

if we use

int time,

we can increase the value like

time++;

if the type is DataElement,how can we increase its value?


---------------------------------------------------------------------------------------------------
DataElement class{

public abstract class DataElement {

public abstract boolean equals ( DataElement otherElement ) ;


public abstract int compareTo ( DataElement otherElement ) ;

public abstract void makeCopy ( DataElement otherElement ) ;

public abstract DataElement getCopy () ;

}


hope someone can help me..u could ask me for further details.tq.

1.) Please use code tags when posting code.
2.) ++ operator is defined only for certaind datatypes like the primitive types. DataElement is your own defined data structure which you define your own rules for. e.g ++ for integers means (generally) increase the value by one. So you need to decide what increase the value of a DataElement means and then use a method to achieve that functionality.
