Answer:

public    static void main(String[] args)

The Java compiler would accept the line. But it looks sloppy to human eyes.

println()

Here is the example program again:

class Hello
{
  public static void main ( String[] args )
  {
    System.out.println("Hello World!");
  }
}

The main method of this program consists of a single statement:

System.out.println("Hello World!");

This statement writes the characters inside the quotation marks to the monitor of the computer system. (The quotation marks are not written.)

The part "Hello World!" is called a string. A string is a sequence of characters. This program writes a string to the monitor and then stops.

QUESTION 4:

(Review: ) Say that the file Hello.java contains the example program. The file is contained in the subdirectory C:\Temp on the hard disk. In order to run it, what two things must be done?
