Let's us understand this, . Operator is used for call methods or variables Methods in Java have parentheses so println is method and out is method out is start with small letter so it is also not class name So out must be variable name or object name Since it is calling a method so it must be object name, Since it is calling from class name System so it is static object It is declared in Java as Public static final PrintStream out; here PrintStream is class Let's a look a program for it public class Goo{ public static String foo; public static void setFoo(String foo) { this.foo=foo; }} int l=Test.foo.length(); for printing length

"System" is a final class from java.lang package. "out" is a variable of type PrintStream inside the System class. "println" is the method that does the printing on the console.
