Question concerning methods

[jim01]

Forgive me for asking a question that should probably be obvious but there is something about methods that confuses me. I've noticed that sometimes a method ends with a {} such as

class Employee

    String name;
    String title;
    double salary;
    boolean married;
    void displayName() {
         System.out.println("Name " + name);
     }

while at other times a method ends with just a ; such as

Employee employee1 = new Employee();
employee1.displayName();

So the question is how do you know when to use {} and when to use ;?

[JosAH]

The first is a method definition; everything between the { ... } makes up the method body; the second is a method call or a constructor call (note the 'new' operator).

kind regards,

Jos

What JosAH said, they aren't the same thing.

In your class file, you're defining the object you want. Everything in between the brackets is what you want to happen when the object you create calls that method. You don't have a limit on how many methods you can have in an object.

Your Employee employee1 = new Employee(); creates a new Employee() object with the method displayName() with the reference of employee1.

Does this answer your question?

creating method ends with {..}
while calling the method it can end with ;
