TAILIEUCHUNG - Lecture Object Oriented Programing - Chapter 2: Introduction to Java applications

Chapter 2 introduction to Java applications. In this chapter you will learn: To write simple Java applications, to use input and output statements, Java’s primitive types, basic memory concepts, to use arithmetic operators, the precedence of arithmetic operators, to write decision-making statements, to use relational and equality operators. | 2 Introduction to Java Applications What’s in a name? that which we call a rose By any other name would smell as sweet. William Shakespeare When faced with a decision, I always ask, “What would be the most fun?” Peggy Walker “Take some more tea,” the March Hare said to Alice, very earnestly. “I’ve had nothing yet,” Alice replied in an offended tone: “so I can’t take more.” “You mean you can’t take less,” said the Hatter: “it’s very easy to take more than nothing.” Lewis Carroll OBJECTIVES In this chapter you will learn: To write simple Java applications. To use input and output statements. Java’s primitive types. Basic memory concepts. To use arithmetic operators. The precedence of arithmetic operators. To write decision-making statements. To use relational and equality operators.
