معامل الجمع

class Main{

public static void main(String[] args){
   int num1 = 10;
   int num2 = 20;
   int num3 = num1 + num2;
   System.out.println(num3);
 }
}

الطرح

class Main{

public static void main(String[] args){
   int num1 = 10;
   int num2 = 20;
   int num3 = num1 - num2;
   System.out.println(num3);
 }
}

الضرب

class Main{

public static void main(String[] args){
   int num1 = 10;
   int num2 = 20;
   int num3 = num1 * num2;
   System.out.println(num3);
 }
}

معامل القسمة

class Main{

public static void main(String[] args){
   int num1 = 10;
   int num2 = 20;
   int num3 = num1 / num2;
   System.out.println(num3);
 }
}

معامل باقي القسمة

class Main{

public static void main(String[] args){
   int num1 = 20;
   int num2 = 4;
   int num3 = num1 % num2;
   System.out.println(num3);
 }
}

معامل الزيادة

class Main{

public static void main(String[] args){
   int num1 = 20;
   ++num1;
   // Does the same job as the above line
   num1 = num1 +1; 
   System.out.println(num3);
 }
}

معامل الإنقاص

int num1 = 20;

--num1;

معامل الإسناد

int count = 0;

الإسناد الإضافي

int count = 0;
count += 10;
// It is an abbreviation of count = count + 10.

معامل الطرح

int count = 20;
count -= 10;
// It is an abbreviation of count = count - 10.

معامل الضرب

int count = 20;
count *= 10;

// It is an abbreviation of count = count * 10.

معاملات المقارنة

معامل المساواة

class Main{

public static void main(String[] args){
   int x = 5;
    int y = 3;
   boolean result = x == y;
   //false
 }
}

معامل عدم المساواة

int x = 5;
int y = 3;

boolean result = x != y;
//true

معامل أكبر من && أصغر من

int x = 5;
 int y = 3; 

//is x greater than y x > y 
//is x less than y x > y  
// is greater or equal than y x >= y  
// is less or equal than y x <= y

المعاملات المنطقية

int x = true;
int y = false;
int status;


// The AND (&&) operator returns true if both values are true.
// returns false for all cases other than that 
status = x && y;
// status will be false.

متابعة المثال

/ *
For the OR (||) operator, one of the two values 
compared to true is sufficient for the result to be true.
* /
status = x || y;
// status will be true.

// In the Logical Not operator, it gets the note equivalent of the logic value we have.
status = !(x || y)

/ *
Although the value inside the parentheses returned true, the not operator made the result false.
* /

status  = !(x && y;);

/ *
Although expression with the AND operator in the parenthesis 
returns false, the not operator ensures that the result is true.
* /
