The System.out object is an instance of the PrintStream class which prints directly to standard output (typically the console window you run your Java program from). This is put here so that programmers have a simple way to display output.
yes ,interface can be defined inside another class
The static field java.lang.System.err is än object of type java.io.PrintStream.The default value of System.err is new FileOutputStream(java.io.FileDescriptor.err).For details, view the source code of System class and review the private initializeSystemClass() method.
A member function of a class can be defined outside the class using scope resolution :: operator Thanks Rajneesh
class is defined in the class
Object Class is the parent class of all classes in java.Every class in the Java system is a descendant (direct or indirect) of the Object class.
Yes, there is a difference in the way a class method is defined depending on where it is declared.
do your apush
Static member variables are local to the class. That is, there is only one instance of a static member variable, regardless of how many objects are instantiated from the class. As such, they must be declared inside the class, and defined outside of the class.
No, class is defined by income.
class A = 16777214 class B = 65634 class C = 254 class D = not defined class E = not defined
Grammaticality there is some difference as the first one, "in class", is a little bit ambiguous. "In class" can mean both "In a class" and "In the class" but unless the class is defined before that statement it usually means "In a class". "In the class" always needs to have the class defined otherwise it is drawing upon unknown knowledge.
A user-defined object is an instance of a user-defined type, typically a class, or an enum.
