Can somebody explain dot operator?

for example: public String example = "Hello"; example.toCharArray();

the dot separates the class name from the method name. It basically tells the compiler which class the method originates in and then which method to use from it.

I hope this helps

The dot operator gives you access to an object's instance variables and methods. In the example you posted, the example variable is an object of type String so you can call methods of the String class on it and the way you access those methods is using the dot operator.

The dot operator is used to call another method and its variables in an object from another class.
