This is one course is a series to prepare for the 1Z0-816: Java SE 11 Programmer II certification exam.Įxplore the structure of Java classes, as well as how to work with Java control statements, Java operators, and loops, along with other topics covered in this 11-video course. The final tutorial involves launching and executing Single-File Source-Code programs and illustrating the enhancements of Shebang mechanisms in Java 11. You will discover how to create and manipulate strings in Java 11, and transform a null or empty string into an empty optional. Next, learn how to create and import packages in Java 11 declare and initialize variables in Java 11 and identify the scope of a variable, and use local variable type inference. Learn to recognize the key features of Java programming language create an executable Java program with a main class and compile and run a Java program by using command-line interface (CLI). Begin with a look at Java and the Java SE 11 enhancements. Discover how to create and run simple executable Java programs, as well as how to create, import, and manipulate packages and strings, and other key topics. In this 13-video course, explore Java SE 11 and its language enhancements, the Shebang mechanism, and key features. Finally, you will learn how to reassign a reference value in a method. As you progress, other key areas include how to add method parameters to overload a constructor, how to pass an Object Reference, and pass a value. Next, you will learn how to use public and private access modifiers, study encapsulation with object-oriented design, and create class setter methods with value checking. Other topics include how to convert strings to their primitive numeric types, ciscover access control, and how to distinguish between the public interface and the internal workings of a class. These include the following: how to create and access static members, how to employ constants to represent unchangeable values, how to change numeric variable types through promotion and casting, and convert data values. During this course, you will discover various static methods and variables and explore a number of topics. Explore object-oriented programming concepts and techniques, in Java.
