hello everyone,
I am a very beginner java user and I have some doubts:
1- see these examples:
Weight weightObject = new Weight();
weightObject.getWeight();
or
Point myPoint = new Point();
myPoint.setX();
myPoint.setY();
The above examples the method is called from an object!!!
2- see these examples:
String number;
int num =Integer.parselnt(number);
or
JOptionPane.showMessageDialog(null,"Message", JOptionPane.ERROR_MESSAGE);
* here JOptionPane and Integer are both classes and methodes (parselnt and showMessageDialog) are methodes called from the class
MQ is:
What is the difference between calling a method from an object and calling a method from the class?Why do we have these two types of methods??
wating for your answers guys... I really need it^_^
thanks in advance.
