Objects and References

The equals( ) method is therefore useful in comparing objects. Here’s an example of a typical equals( ) method:

class Box{

// same accessor/modifier methods seen in previous slides

public boolean equals (Object oTemp) {

boolean bSame = false;

if (oTemp instanceof Box) {

Box bTemp = (Box) oTemp;

if ( getLength() == bTemp.getLength() &&

getWidth() == bTemp.getWidth() &&

getHeight() == bTemp.getHeight() )

bSame = true;

}

return bSame;

}// equals
