Arithmetic Operators in java

Arithmetic Operators in Java :
Arithmetic operators are most well known programming basics. It is simple consists of summation, subtract, multiplication, division and mod. In java these operators are applied on all primitives of types short, integer, long, float, and double.

Plus- Operator (+)

Plus operator is used to sum variables as follows:
Example:
java code

int x=5;
int y=43;
int z=x+y;

You sum variables from different datatypes but to be attention to the lose of precision and casting:
java code

float x=54.3f;
    int y=4;
    long z=53l;
    double sum=x+y+z;

Or using casting :
java code

float x=54.3f;
    int y=4;
    long z=53l;
    int sum=(int) (x+y+z);

You can use the plus operator in suffix or prefix manner but here you work on one variable only, as follows:

Suffix , add the double plus the operators before the variable name:

This means that the variable X one is increased by one before assigning its value to variable y.
Prefix, add the double plus operators after the variable name:
java code

int y=x++;

This means that the variable X one is increased by one after assigning its value to variable y.
You can use the prefix and suffix at the same time as:

Mines - Operator (-)

Used to subtract two variables
Example :
java code

int x=5;
int y=4;
int z=x-y

It also has suffix and prefix same as Plus operator

Example :

but it decreases the value of x by 1 .

Star- Operator (*)

Binary operator to multiply two variables or values :
Example :
java code

int x=5;
int y=4;
int z=x*y;

multiply the value of x by y .

Divide- Operator (/)

Example :


divide the value x by y .

Mod- Operator (%)

Mod is used to get the reminder of division between two numbers.
Example :

For Example:
java code

int x=13;
  int z=54;
  int y; 
    y=z%x;
    System.out.println(y);

The output is :

Get the remainder of dividing x ,y
