String class
bold = mandatory

0 or more methods to the methods it inherits from its superclass final class a list of variables, called instance variables, corresponding to data that will be present in each instance its members from access by other classes or objects using an access modifier Variables and Data Types the internals of a computer system such as 'Record', 'Table', 'Data', 'Structure', or 'Information' any public class in other packages string
if a class is not declared public
then it is accessible only to members of the same package
only one superclass implementation for all its instance methods unless the class is abstract its own source file several similar objects behaviour from its superclass data associated with each object to increase system security by preventing system subversion
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
create an instance of it more than one interface a package elements as follows:
class variables
instance variables
constructors
the most important public methods
methods that are simply used to access variables
private methods
Object class a class type whose instances are the values of the class type 1 class definition
public
or private
or protected
the keyword final before the keyword class in the class declaration zero-based indexing methods that are inherited from the class's superclass
class classname
{ // declarations of variables
// declarations of constructors
// declarations of other methods with public ones first
}
reusability
modularity
1 named package rather than the default package specification constructor abstract
