... int intVar1 = 27; int intVar2 = intVar1; if(intVar1 == intVar2) System.out.println("They're equal"); This is the same as the syntax in C and ... that Java doesn't use pointers. Although it surprises some people, pointers aren't necessary for the creation of complex data structures and algorithms. In fact, eliminating p...
