In the particular case of the System class, the out field is a public static field of type PrintStream (it holds an instance of a PrintStream statically which has a println() method) and this is what the javadoc says about it: The standard output stream. This stream is already open and ready to accept output data.The only things allowed outside method and constructor declarations are declarations of fields. Since System. out. println() is not a field declaration, it's not allowed. It needs to be inside an executable block of code to be executed. Otherwise there's no way to know when to execute it. It doesn't have to be a method. system out println static method

The modifiers public and static can be written in either order (public static or static public), but the convention is to use public static as shown above.

PrintStream. println is a method of java. io. PrintStream. This method is overloaded to print message to output destination, which is system out println static method System. out. println (). So now we know that out is a static member variable belonging to the System class. Noticing the fact that println () is clearly a method, we can further classify the out in System. out. println (). We have already reasoned that out is a static variable belonging to Aug 23, 2017 System is a class in the java. lang package. . out is a static member of the System class, and is an instance of println is a method of method is overloaded to print message to output destination, which is typically a console or file. Question on System. out. println method (static Vs nonstatic) Static block is called first while loading the class in the jvm. You can call static method inside the nonstatic method using the class name and to call a non static method inside a static block, we have to call the method using their objects. I agree what you said. What is System. out. println. System. out. println is a Java statement that prints the argument passed, into the System. out which is generally stdout. System is a final class in java. lang package. out is a static member field of System class and is of type PrintStream. Its access specifiers are public final.
