After a slight delay the prompt will return. During normal program execution in Java, the caller method calls the worker method, the worker method performs an action and the execution returns to the caller method. Classes are grouped into packages to ease the management of the system. To deploy a Java application, you put the necessary files into a JAR file.

Most other cert books I’ve read assume you have some knowledge already. This book is more of a competitor of “Thinking in Java” and Deitel & Deitel. However if you read the book, do the exercises and answer the questions in each chapter, you will be well prepared for the cert so it is a cert book in that space. Use System.out.println to print the listOfNames object.

Click the java se7 fundamentals Out button to return to the next line of code in the ShirtTest class. The displayInformation method will have completed. Run the debugger by right-clicking on the ShirtTest file in the Projects window and selecting Debug File. The debugger starts the program and stops at the breakpoint. In the Editor panel you should now see a different icon that points with a green arrow to the line of code. The Java source file for the new class now appears in the editor ready for you to fill in the details.

Ensure that the dashes appear between the third and fourth digits and between the sixth and seventh digits. You have now experienced some of the most commonly used features of a typical IDE Debugger. You may wish to use the debugger in remaining labs to help you diagnose and fix problems you may experience in your programs. Close the Practice04 project in NetBeans. In the Projects window, right-click Practice04 and select Close from the context menu. The arrow icon is pointing to the first executable line of code within the displayInformation of the Shirt class.

• It is an intro to Java book that prepares you for the cert.
• Packages, JARs and deployment, two-tier and three-tier architecture, and modifications and enhancements to a sample application are also covered.
• Copyright © 2011, Oracle and/or its affiliates.
• − The third button Continue the execution, either to the next breakpoint or to the end of the program.
• He writes Java-based courseware and contributes content for Oracle’s certification exams, as well as leading seminars on Java EE, performance tuning, and adopting Java-based software.

Now run the project by clicking the Run button on the main toolbar. This line of code has not yet been executed. Several other changes have occurred in the NetBeans window.

The Java Language Specification, Java SE 7 Edition

Packages, JARs and deployment, two-tier and three-tier architecture, and modifications and enhancements to a sample application are also covered. The book also includes best practices and opinions which are good for jumping in. For example, Michael explains doubles aren’t good choices for real world objects. (I work for a bank.) However, he then implies you should adapt a primitive type for money rather than using BigDecimal. While I agree that is probably out of scope for an intro book, it still jumped out at me. “Java SE 7 Programming Essentials” stands apart from the other OCAJP certification books because it isn’t a certification book. It is an intro to Java book that prepares you for the cert.

− The fifth button, Step Over Expression, allows you to step over an entire expression to the next line of code in the current class. Since you are a new programmer, so I would like to suggest you to collect OCA SE 7 Certificate Guide by Mala Gupta for OCA 1Z0-803 exam. I was helped by this book a lot, this is well covered the exam topics and simply explained.
