Example
Operator Description Syntax Output
(int a = 10, b = 2)
Returns the result to the operand
a /= b a = 5
/= present on the left hand side after a /= b
a /= 5 a = 2
performing division
Returns the remainder to the operator
a %= b a = 0
%= present on the left hand side after a %= b
a %= 6 a = 4
performing division
WRITING SOME MORE PROGRAMS
Let us write programs using Java's various concepts.
Program 1: Program to calculate 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
Output
area = length * width;
// Perimeter of rectangle = 2 * (length + width)
perimeter = 2 * (length + width);
System.out.println("Area of the rectangle is: " + area);
System.out.println("Perimeter of the rectangle is: " +
perimeter);
}
}
Program 2: Program to find the amount to be paid.
public class Amount {
public static void main(String args[]) {
int unitPrice, units, amount;
unitPrice = 20;
units = 100;
Output
amount = unitPrice * units;
System.out.println("Total amount to be paid: " + amount);
}
}
