Such a plus sign should not be necessary. In Java, an expression like (+x) is equivalent to (x) (with or without the quotation marks).

Is java's println a method?
Consider the following statement: System.out.println ("string to be printed"); The statement begins with System.out. This is a constant that represents the default output mode, which in this case is the screen. The constant helps to read and display the data in a Java program. The output is generated using the built-in println() method. The string that is assigned to the println() method is displayed when the statement is executed. For example, class Class2 { public static void main (String args[]) { System.out.println("Here is your string"); } } The above program will show the following output: Here is your string
What is use of dot operator in java?
"the dot" connects classes and objects to members. The places where you use it in what I cover are:(1) when you are connecting an object reference variable to a method. The Extending Existing Classes lesson introduces the dot operator for this use, and(2) when you are connecting a class name to one of its static fields. An example of this is the dot between "System" and "out" in the statements we use to print stuff to the console window. System is the name of a class included in every Java implementation. It has an object reference variable that points to a PrintStream object for the console. So, "System.out.println( "text") invokes the println() method of the System.out object.
