Arithmetic Operators

Arithmetic Operators

  • Arithmetic Operators are,
    • +    Additive (also for String concatenation)               
    • -     Subtraction
    • *    Multiplication                                          
    • /     Division
    • %   Remainder 
  • By seeing above symbols hope everyone knows what ll happen with corresponding operators. Appreciate for your remembrance.
+    Addition   
   adds one value to another value and produces the result
   Joins the two String values and gives us result
-      Subtraction
   Subtracts one value from another value and produces the result
     Multiplication
   Multiplies one value with other value and produces the result
     / Division
   It divides the value  and produces the result
    % Remainder
   The remainder of the Division operation

Program         :       All arithmetic Operations
Program name :       OpeDemo1.java
Output             :        
                             x + y = 30
     x - y  = -10
     x * y = 200
     y / x  = 2
     x % 3= 1

class OpeDemo1
{
        public static void main(String args[])
        {
            int x = 10;
            int y = 20;

            int add= x + y;

            System.out.println("x + y = " + add);

            int sub = x - y;

            System.out.println("x - y = " + sub);

            int mul = x * y;

            System.out.println("x * y = " + mul);

            int division= y / x;

            System.out.println("y / x = " + division);

            int mod = x % 3;

            System.out.println("x % 3 = " + mod);
        }
}

Compile     :            javac OpeDemo1.java
Run           :            java OpeDemo1
Output       :        
                             x + y = 30
     x - y  = -10
     x * y = 200
     y / x  = 2
     x % 3= 1

Program        :       + Operator using with String objects
Program name :       OpeDemo2.java
Output            : 
                             Hello Please dont sleep

class OpeDemo2
{
        public static void main(String args[])
        {
              String firstValue = "Hello";
              String secondValue = "Please dont sleep";
              String result= firstValue + secondValue ;
        }
}

Compile     :            javac OpeDemo2.java
Run           :            java OpeDemo2
Output       : 
                             Hello Please dont sleep
