Is lesson me hum seekhenge:

• Operators kya hote hain
• Arithmetic Operators
• Assignment Operators
• Logical Operators
• Relational Operators
• Unary Operators
• Order of Operations (BODMAS Rule)

Java me operators special symbols hote hain jo variables aur values par operations perform karte hain.

Example:

5 + 3
10 > 4
a = b

Arithmetic operators mathematical calculations ke liye use hote hain.

public class ArithmeticExample {

    public static void main(String[] args) {

        int a = 10;
        int b = 5;

        System.out.println(a + b);
        System.out.println(a - b);
        System.out.println(a * b);
        System.out.println(a / b);
        System.out.println(a % b);

    }

}

Assignment operator ka use value assign karne ke liye hota hai.

public class AssignmentExample {

    public static void main(String[] args) {

        int a = 10;

        a += 5;
        System.out.println(a);

        a *= 2;
        System.out.println(a);

    }

}

Output

Relational operators comparison ke liye use hote hain.

Ye result true ya false return karte hain.

public class RelationalExample {

    public static void main(String[] args) {

        int a = 10;
        int b = 5;

        System.out.println(a > b);
        System.out.println(a < b);
        System.out.println(a == b);
        System.out.println(a != b);

    }

}

Output

true
false
false
true

Logical operators multiple conditions check karne ke liye use hote hain.

public class LogicalExample {

    public static void main(String[] args) {

        int age = 20;
        boolean hasLicense = true;

        System.out.println(age >= 18 && hasLicense);
        System.out.println(age >= 18 || hasLicense);
        System.out.println(!hasLicense);

    }

}

Output

true
true
false

Unary operator single operand par operation karta hai.

public class UnaryExample {

    public static void main(String[] args) {

        int a = 5;

        a++;
        System.out.println(a);

        a--;
        System.out.println(a);

    }

}

Output

Java expressions evaluate karte waqt BODMAS rule follow karta hai.

BODMAS ka matlab:

B → Brackets
O → Order (Power)
D → Division
M → Multiplication
A → Addition
S → Subtraction

public class OrderOfOperations {

    public static void main (String[] args) {

        System.out.println(10 - 5 * 4);

        System.out.println(10 * 5 * 2 + 5 / 2 - 2); // BODMAS Rule Follow

        System.out.println(10 / (4 / 2)); // BODMAS Rule Follow

    }

}

10 - 5 * 4

Step:

5 * 4 = 20
10 - 20 = -10

Output

-10

10 * 5 * 2 + 5 / 2 - 2

Step:

10 * 5 = 50
50 * 2 = 100
5 / 2 = 2
100 + 2 = 102
102 - 2 = 100

Output

100

10 / (4 / 2)

Step:

4 / 2 = 2
10 / 2 = 5

Output

5

Is lesson me humne seekha:

✔ Arithmetic Operators
✔ Assignment Operators
✔ Relational Operators
✔ Logical Operators
✔ Unary Operators

Operators Java programming ka fundamental concept hain aur almost har program me use hote hain.

Next lesson me hum seekhenge:

• Conditional Statements
• if
• if-else
• else-if
• Nested if
