3. Methods: a)Method name must start with lowercase b) if there are multiple words in the name, then you need to use Uppercase for starting letters for these words except for the starting word. This is called as lowerCamelCase. example:-void myMethod() { }

4. Object/Variables:- a)Object/ variables must start with lowercase and if there are multiple words in the name, then you need to use Uppercase for starting letters for the words except for the starting word. This is called as lowerCamelCase. ex:-String myName; MyClass myObject;

5. Constant Variables: a)constant variables are declared using “static final” modifiers. And such variables must contain only UpperCase characters and multiple words must be seperated using ‘_’. example:-static final char END_OF_FILE
