# Operators in Java(part1)

--

Hi readers! This is my fourth article and it is about Java operators.I hope you all have read my other three articles and I was really happy to see many of your comments and opinions which made me forced to write my fourth article.

## Operators and Operands

•An ** operator** is a function that has a special symbolic name and is invoked by using that symbol with an expression.A value used on either side of an operator is called an

**operand**.

`int x=6+3;`

In above example + is an operator.6 & 3 are operands

## TYPES OF OPERATOR

- Arithmetic Operator [ +, -, *, /, % ]
- Assignment Operator [ =, +=, -=, *=, /=, %= etc…]
- Increment / Decrement Operator [ ++, — ]
- Relational Operator [ >, <, >=, <=, !=, == ]
- Logical Operator [ &&, ||, ! ]
- Bit wise Operator [ &, |, ^, ~ ]
- Conditional Operator [ ? : ]

Also according to the way of we are using operators, they can be categorized as follows.

- Unary(++, — , ==, !)// use one operand
- Binary(+, -, /, *, %) // use two operand
- Ternary( ? : ) // use three operand

**Arithmetic Operators**

Arithmetic operators are used in mathematical expressions in the same way that they are used in algebraic equations.

**Addition**

The + operator adds together two values such as two constants, a constant and a variable, or a variable and a variable. Here are a few examples of addition

`int sum1 = 50 + 10;//two constants `

int sum2 = sum1 + 66;//constant and a variable

int sum3 = sum2 + sum2;//two variables

ex1:

`int x=2;`

int y=7;

int z=x+y;//answer is 9

int z="x"+"y";//error

String z="x"+"y"//answer is xy as collecting two strings

ex2:

` int num1 =50+10;//answer is 50+10=60`

int num2=num1+66;//answer is 60 +66 =126

int num3 =num2+num2;//answer is 126+126 =252

## Subtraction

The — operator subtracts one value from another.

`int num1=1000 - 10; //answer is 990`

int num2=num1 - 5; //answer is 985

int num3=num1 - num2;//answer is 5

## Multiplication

The * operator multiplies two values.

`int sum1 = 1000*2 //answer is 2000`

int sum2 = sum1*10 //answer is 20,000

int sum3 = sum1*sum2 // answer is 40,000,000

## Division

The / operator divides one value by another.

`double x=3;`

double y=2;

double z=x/y; //answer is 1.5

## Modulo

The **modulo **(or remainder) math operation performs an integer division of one value by another, and returns the remainder of that division.

The operator for the modulo operation is the percentage (%) character.

ex1:

`int value = 23;`

int res = value % 6; // res is 5

ex2:

`double x=3;`

double y=2000;

double z=x%y; // answer is 3.0

In this article I explained about what are operators,operands,types of operators and mainly about Arithmetic operators with examples.In next article I would like to write about other types of operators which that we should clearly understand.Your opinions are highly appreciated.Thank you.Keep in touch.
