Title: Interfaces: Exam questions tests - Sun Certified Java Programmer 310-065 - Lesson 57
Duration: 16 minutes
Summary: In this video, we are continuing with the sample exam. This is sample 1. There is another set of 75 questions coming after this set. We are covering a random sample of questions that encompasses interfaces, methods, var-args, constructors, and loops. The tricky part about interfaces in the exam is that all the methods are correctly implemented and the appropriate access modifies (public…) are being used. This concept applies to the constructors as well. Sometimes one constructor will make a call to another (using the keyword ‘this’ for example), while the other constructor is not implemented in the class. Watch out for these tricky questions! Finally, we will encounter code that makes use of loops, break statements and break with a label.
Methodology of the development of example: Good coding standard and simplified design to prepare for the Java programmer certification exam CX-310-065.
Technology Used: Java – Core Concepts.
Keywords: class, object, interface, implements, var-args , constructors, while loop.
Interfaces can define methods as public. It is redundant, and not encouraged, but it will compile.
