Multiplication of Numbers

SOURCE CODE

class Multiplication {
public static void main(String args[]) { // start of main() method.
int a=9, b=12, c;  // initializing a & b of type integer.
c = a * b; //Multiplying a & b using "*" operator and storing in c.
System.out.println("Multiplication is : "+c);  // printing result.
} // end of main() method.
} // end of class.

OUTPUT

Multiplication is : 108

NOTE:-

 Instead of using
                c = a * b;

              System.out.println("Multiplication is : "+c);
you can use following single line of code
                System.out.println("Multiplication is : "+(a*b));
If you want to use above single line then you don't have to declare the third variable i.e. c.

You can multiply multiple numbers at a time.

Subtraction of Numbers

SOURCE CODE

class Subtraction {
public static void main(String args[]) { // start of main() method.
int a=10, b=14, c;  // initializing a & b of type integer.
c = a - b; //subtracting b from a using "-" operator and storing in c.
System.out.println("Subtraction is : "+c);  // printing result
} // end of main() method.
} // end of class.

OUTPUT

Subtraction is : -4

NOTE:-

   Instead of using
                c = a - b;

              System.out.println("Subtraction is : "+c);
you can use following single line of code
                System.out.println("Subtraction is : "+(a-b));
If you want to use above single line instead of those two then you don't have to declare the third variable i.e. c.

Sum Of Two Numbers

SOURCE CODE

class addition {
public static void main(String args[]) { // start of main() method.
    int a=10, b=14, c; // initializing a & b of type integer.
    c = a + b; // adding a & b using "+" operator and storing in c.
    System.out.println("Addition : "+c);     // printing result
}         // ending of main() method.
}      // end of the class.

OUTPUT

Addition : 24

NOTE:-

   Instead of using
                c = a + b;

System.out.println("Addition : "+c);
you can use following single line of code
                System.out.println("Addition : "+(a+b));
If you want to use above single line then you don't need to declare the third variable i.e. c.

Operators in JAVA

Operators are the thing which operates on variable to produce results. They manipulate both the data and variables. JAVA provides wide variety of operators. Those are as follows:-

1)      Arithmetic Operators:-
These operators are used on mathematical expressions. These operators are as follows:-

Sr. No.	Operator	Meaning	Sample Program
1	+	Addition	Click HERE
2	-	Subtraction	Click HERE
3	*	Multiplication	Click HERE
4	/	Division	Click HERE
5	%	Modulus	Click HERE
6	+=	Addition Assignment	Click HERE
7	-=	Subtraction Assignment	Click HERE
8	*=	Multiplication Assignment	Click HERE
9	/=	Division Assignment	Click HERE
10	%=	Modulus Assignment	Click HERE
11	++	Increment	Click HERE
12	--	Decrement	Click HERE

2)      Bitwise Operators:-
These operators are operated on type int, long, short, char and byte. These operators operate on individual bit of operand. These operators are as follows:-

Sr. No.	Operator	Meaning	Sample Program
1	~	Bitwise NOT	Click HERE
2	&	Bitwise AND	Click HERE
3	|	Bitwise OR	Click HERE
4	^	Bitwise EXCLUSIVE OR (XOR)	Click HERE
5	&=	Bitwise AND Assignment	Click HERE
6	|=	Bitwise OR Assignment	Click HERE
7	^=	Bitwise EXCLUSIVE OR (XOR) Assignment	Click HERE
8	>>	Shift right	Click HERE
9	>>>	Shift right zero fill	Click HERE
10	>>=	Shift right Assignment	Click HERE
11	>>>=	Shift right zero fill Assignment	Click HERE
12	<<	Shift left	Click HERE
13	<<=	Shift left Assignment	Click HERE

3)      Relational Operators:-
These operators used to decide the relation between the operands. These operators are as follows:-

Sr. No.	Operator	Meaning	Sample Program
1	==	Equal to	Click HERE
2	!=	Not equal to	Click HERE
3	>	Greater than	Click HERE
4	>=	Greater than or equal to	Click HERE
5	<	Less than	Click HERE
6	<=	Less than or equal to	Click HERE

4)      Logical Operators:-
Logical operators are used to combine operands. These operators are as follows:-

Sr. No.	Operator	Meaning	Sample Program
1	&&	Logical AND	Click HERE
2	||	Logical OR	Click HERE
3	!	Logical NOT	Click HERE
4	^	Logical XOR	Click HERE
5	?:	Ternary if - else	Click HERE

5)      Assignment Operators:-
These operators are used to assign a particular value to the operator or to check the value of particular operand.

Sr. No.	Operator	Meaning	Sample Program
1	=	Assign the value	Click HERE
2	==	Check the value	Click HERE
3	===	Check the value with case sensitive	Click HERE
