The fifth SCJP objective is primarily about Java operators. This chapter briefly discusses all the java operators and how they are used. This chapter also prepares a base for the next chapter, in which we will discuss the conversion, casting and arithmetic promotion of Java operands. Specifically this chapter covers the 5.1 (partially), 5.2 (partially) and 5.3 sections of SCJP objectives.
