Java程序辅导

Welcome: A First Java Program in Eclipse 
 To get Eclipse on your local machine, in D2L view Content > Miscellany > EclipseDownload 
Implement and Run a Welcome Program 
 If you are in the lab and you haven’t already done so, login to your Windows account  
 Click the Eclipse Icon  
 Eclipse will start and offer a Welcome page, which you should close (if it is visible) 
 While in Eclipse, select Windows > Preferences > Expand Java > Select Compiler  
 Create a new project by clicking on File > New > Project 
 
 Make sure Java Project is selected, and then click the Next (at bottom) 
 
 
 
 Name your project with a name indicating the lab# and your name: Lab1_Chris 
 
  Create a class with File > New > Class 
 
 After Name: type the name of the class you want to create. For project 1, the first class you 
create will be called Welcome. After you type that in, click Finish (at bottom).  
        
 Type in the following code as it is shown below. As you type, you may encounter squiggly 
red lines under portions of your code. This is the compiler telling you that you may have an 
error. To be sure, type the entire line as shown below. For help, look at the messages in the 
Tasks view under your program (or let the mouse hover over the error).    
  Once everything is typed in, save the file by going to File > Save (or Ctrl-S for short). 
Saving the file compiles the code into a class file and updates the error messages. Fix any 
errors you may have before you go on.  
 Next, go to Run >Run As > Java Application 
 
 At the bottom of the screen in the Console box, you should see some output that says  
 
         Welcome. What is your name?    
 
 Click on the console window to the right of this prompt  
 Type in your name (input is green like Jane) and press the enter key  
 The dialog should look like this (with a different name unless your name is Jane): 
 
Welcome. What is your name? Jane 
Hello Jane! I hope you are well :-) 
Print this File for your Turnin 
 Make sure your name is in the comment at the top of the file.  
 From Eclipse, select File > Print 
 If you are in a CS lab (228 or 930 Gould Simpson), locate the nearest printer name and select that 
printer from the list of printer names in the dialog.
