To implement the logic of a program, we may some operators to solve the problems. These operators are
used in the expressions which also contain identifiers, values or literals. Operators are symbols to instruct the
compiler to execute some operations or calculations. Let’s learn about operators and their types in detail.
5.1 OPERATORS
An expression has two parts: Operand and Operator. The variables or values that are used in the expression are
called Operand and the symbols on which the operand works such as + (addition), – (subtraction), etc. are known
as Operators. For example,
c = a + b
Here, a and b are operands and + is the operator.
Java usually has a group of built-in operators with common meaning assigned to them, though in some special
cases it allows programmers to assign different meanings. Let us understand with an example:
double m=34.76, n= 3.6, r;
int a = 1, b = 4, c;
r = m * n;
c = b - a;
System.out.println(“The product is:” +r);
System.out.println(“The difference is:” +c);
