The clipboard is a section of the computer's main memory that is used to copy data between various application programs.
Step 3 is to copy the characters of the program from the Web browser's window into the clipboard. Later (in step 4) the characters will be copied from the clipboard into Notepad. Step 3 involves some skills using Windows that you may not have used, yet. Here is the example program, again:
class HelloPlanets { public static void main ( String[] args ) { String[] planets = {"Mercury", "Venus", "Earth", "Mars", "Jupiter", "Saturn", "Uranus", "Neptune", "Pluto"}; for ( int j=0; j< planets.length; j++ ) { System.out.println("Hello " + planets[j] +"!" ); } } }
First, the characters of the program must be "highlighted" by clicking the mouse on the first character, and dragging to the last character:
Be careful not to click the mouse again in the window or you will cancel your selection. (But you can always do it again.) After you have done this, you should see something like the following:
The last part of Step 3 is to copy the selected text into the clipboard.
Look at the top menu bar of your browser window. There are a list of menus, such as "File", "Edit", "View", "Go", and others. Which one (do you imagine) will be used to copy to the clipboard?
