The parentheses are used in methods to specify arguments. Some methods don't use arguments; but it would in fact be more confusing, not less, to omit the parentheses in this case - because the parentheses give some kind of consistency.
The parentheses also help make it clear when something written after a dot is a field, and when it is a method. For this reason, in languages that allow you to either write or not write the parentheses for methods without arguments, I would always write them, for clarity and consistency.

Since the Java program is basically a text file, you can write it in any text editor (although using a Java IDE, or an IDE with support for Java, does give you certain advantages).
