Java, an object-oriented programming language, is one of the most widely used development languages in the world today. It allows programmers to create objects that can interact with other objects to solve a problem. This course covers working with classes and objects including array objects, and introduces the NetBeans IDE. It also covers manipulating and formatting data in a Java program with classes such as String and StringBuilder and covers type casting and promotion. This course can be used to as part of preparation for the Oracle exam 1Z0-808, Java SE 8 Programmer, to obtain the Oracle Certified Associate level certification.
