We know that println() method is available in PrintStream class of java.io package.To call any method of a class in java we required object of that class if the method is not static.we know println() is not static,so we required object of PrintStream class object.'System' is class in java and 'out' is static field in 'System' class.In java all static methods and static fields are accessed with class name,so 'out' is static field we access lke System.out that returns the object of PrintStream class with that PrintStream class object we can call methods of PrintStream class.Hence,we call like System.out.println(" "); when we execute this instruction we get one blank space after executing contol goes to next line.
