Assignment Operators
Assignment operators are used to assign values to operands. One of the most commonly used
assignment operators is equal (=). This operator can also be used with arithmetic operators
to make the shorthand assignment operators. The shorthand assignment operators perform
calculations and assign the result to the variable present on the left hand side of the operator.
Example
Operator Description Syntax Output
(int a = 10, b = 2)
Returns the result to the operand present
a += b a = 12
+= on the left hand side after performing a += b
a += 5 a = 15
the addition operation.
Returns the result to the operand present
a -= b a = 8
-= on the left hand side after performing a -= b
a -= 5 a = 5
the subtraction operation.
Returns the result to the operand present
a *= b a = 20
*= on the left hand side after performing a *= b
a *= 5 a = 50
the multiplication operation.
Returns the result to the operand present
a /= b a = 5
/= on the left hand side after performing a /= b
a /= 5 a = 2
the division operation.
Returns the remainder to the operator
a %= b a = 0
%= present on the left hand side after a %= b
a %= 6 a = 4
performing the division operation.

i + WRITING SOME MORE PROGRAMS
Let us use the various concepts of Java to write programs.
Program 1: Write a program to calculate the area and perimeter of a rectangle.
public class Calculate {
public static void main(String args[]) {
int length, width, area, perimeter;
length = 5;
width = 10;
// Area of rectangle = length * width
area = length * width; Output
