Lab 1: Java Basics Except where otherwise noted, the contents of this document are Copyright 2010 Stuart Reges and Marty Stepp. lab document created by Whitaker Brand and Marty Stepp --> Basic lab instructions You may want to bring your textbook to future labs to look up syntax and examples. Stuck? Confused? Have a question? Ask a TA for help, or look at the book or past lecture slides. We encourage you to talk to your classmates for help. You probably won't finish all of the exercises. Do as much as you can within the allotted time. You don't need to keep working on these exercises after you leave the lab. Before you leave today, make sure to check in with one of the TAs in the lab to get credit for your work. Today's lab Goals for today: practice writing, compiling, and running basic Java programs with println statements learn about the jGRASP editor software gain familiarity with syntax errors and debugging learn about various useful CSE 142 online tools and resources practice submitting a program through the course turnin system Exercise 1: Compile and run a program in jGRASP Recall from lecture: A Java program must be compiled, or translated into binary instructions. Then it can be executed or run. When you run a program, it displays output messages to the user in a text window called a console. For our first exercise, let's compile and run a short program that we will provide to you. (See the following slides.) If you get stuck, ask a classmate or TA for help. Exercise 1 - run jGRASP and create file Run the jGRASP editor from the Start Menu of the lab computer (or run it from your own laptop, if you brought one). In jGRASP, create a new Java program: Click File → New → Java from the top menu. An empty white text window should appear in jGRASP. continued on next slide... Exercise 1 - copy/paste Copy and paste the following program into jGRASP: public class MyFirstProgram { public static void main(String[] args) { System.out.println("Hello, world!"); System.out.println(); System.out.println("This

Exactly. Use our Output Comparison Tool web page to check if your output is correct. Go to the CSE 142 Labs page. Click the "Output Comparison Tool link." Select Exercise 4 from the list. The expected output should appear. Go back to your program. Run it and copy/paste its output from jGRASP's console into the "Actual Output" box of the web page. Click Compare on the page. Does your output match? If not, fix the program and try again. If you had to fix any output, turn in the program again. Exercise 5: Indentation Programs should be indented properly to make them easier to read. { brace → increase indent of following lines by one tab } brace → decrease indent of that line and following lines by one tab The following program has poor indentation. Paste it into jGRASP and fix it. public class Icky {public static void main(String[] args) {System.out.println("Properly indented programs"); System.out.println("look ever so much better!"); System.out.println("please fix me"); System.out.println("and make me beautiful again");} } Exercise 6: Practice the Indenter Tool In CSE 142 you can use a web page called the Indenter Tool to automatically correct the indentation of a program. Go to the CSE 142 Labs web page. Click the link that says "Indenter Tool." Go back to your program. Select all of the code and copy/paste the code into the text box of the web page. Click Fix Indendation on the page. The code should now be indented correctly. Copy/paste it back into jGRASP and save the file. Exercise 7: What's the output? How many lines of output are produced (including blank lines)? public class Tricky { public static void main(String[] args) { System.out.println("Testing, testing,"); System.out.println("one two three."); System.out.println(); System.out.println("How much output"); System.out.println(); System.out.println("will there be?"); }} Answer: 6 lines. The blank lines in the code don't count, but the System.out.println(); statements do. Exercise 8: Syntax errors The following program contains 11 errors! What are they? 1 2 3 4 5 6 7 8 9 public class Tricky public static main(String args) { System.out.println(Hello world); system.out.Pritnln("Do you like this program"?); System.out.println() System.println("I wrote it
