This chapter introduces the basics of Java program design. It presents a series of programs that interact with their users through text-based outputs and inputs. The chapter also introduces the Java primitive types. These types and their associated operators enable programs to create and manipulate integer, floating-point, and character values and variables. | Java basics Copyright © The McGraw-Hill Companies, Inc.

Consequently, different computers use different machine languages. The machine language understood by Intel’s Pentium processor is quite different from the machine language understood by IBM’s PowerPC® processor. A major problem with machine language programming is that it is very tedious and error prone to write directly in binary codes. Slightly less tedious is assembly language programming. An assembly language is a symbolic language for coding machine language instructions. Like machine language programmers, assembly language programmers must have a complete understanding of basic operations of the machine. Furthermore, because the corresponding machine operations are so primitive, for even very simple tasks, assembly language programs can be quite long and complicated.
