Arithmetic operators
- 2. Arithmetic operators Arithmetic operators process numerical values and return a single numeric value. The Java programming language provides operators that perform addition, subtraction, multiplication, and division.
- 3. Operator Description Example a = 10, b = 2, c = 0 + Addition c = a + b c = 10 + 2 c = 12 - Subtraction c = a - b c = 10 - 2 c = 8 * Multiplication c = a * b c = 10 * 2 c = 20 / Division c = a / b c = 10 / 2 c = 5 % Modulus c = a % b c = 10 % 2 c = 0 ++ Increment c = ++a c = 10 + 1 c = 11 -- Decrement c = --a c = 11 - 1 c = 10
- 7. Increment operator When we add any value to an existing value ; Such as; A++ ++A POSTFIX NOTATION Increment After the operand A++ PREFIX NOTATION Increment Before the operand ++A It adds 1 by default or additionally by demand.
- 8. DECREMENT OPERATOR When we subtract any value to an existing value ; Such as; A-- --A POSTFIX NOTATION Decrement After the operand A-- PREFIX NOTATION Decrement Before the operand --A It subtracts 1 by default or additionally by demand.
- 9. PROGRAM: <html> <head> <script language="javascript"> var n,a,b; a=prompt(“enter a number”); a=++n; b=n++; </script> </head> <body> <script language=“java script”> Document.writeln(n); Document.writeln(a); Document.write(b); </script> </body> </html>
