             Unleashing Java Magic: Where Every Line of Code Comes Alive

1.Java Arithmetic Operators

Write a  Java Operators Program

PROGRAM: Java Operators Program

/* Java Operators Program */

class Main {
public static void main(String[] args) {

// declare variables
int a = 12, b = 5;

// addition operator
System.out.println(“a + b = ” + (a + b));

// subtraction operator
System.out.println(“a – b = ” + (a – b));

// multiplication operator
System.out.println(“a * b = ” + (a * b));

// division operator
System.out.println(“a / b = ” + (a / b));

// modulo operator
System.out.println(“a % b = ” + (a % b));
}
}

2.Java Assignment Operators

Write a  Java Assignment  Operators Program

PROGRAM: Java Assignment Operators Program

/* Java Assignment  Operators Program */

class Main {
public static void main(String[] args) {

// create variables
int a = 4;
int var;

// assign value using =
var = a;
System.out.println(“var using =: ” + var);

// assign value using =+
var += a;
System.out.println(“var using +=: ” + var);

// assign value using =*
var *= a;
System.out.println(“var using *=: ” + var);
}
}

3. Java Relational Operators

Write a  Java Relational  Operators Program

PROGRAM: Java Relational Operators Program

/* Java Relational  Operators Program */

class Main {
public static void main(String[] args) {

// create variables
int a = 7, b = 11;

// value of a and b
System.out.println(“a is ” + a + ” and b is ” + b);

// == operator
System.out.println(a == b); // false

// != operator
System.out.println(a != b); // true

// > operator
System.out.println(a > b); // false

// < operator
System.out.println(a < b); // true

// >= operator
System.out.println(a >= b); // false

// <= operator
System.out.println(a <= b); // true
}
}

4. Java Logical Operators

Write a  Java Logical  Operators Program

PROGRAM: Java Logical Operators Program

/* Java Logical Operators Program */

class Main {
public static void main(String[] args) {

// && operator
System.out.println((5 > 3) && (8 > 5)); // true
System.out.println((5 > 3) && (8 < 5)); // false

// || operator
System.out.println((5 < 3) || (8 > 5)); // true
System.out.println((5 > 3) || (8 < 5)); // true
System.out.println((5 < 3) || (8 < 5)); // false

// ! operator
System.out.println(!(5 == 3)); // true
System.out.println(!(5 > 3)); // false
}
}

5. Java Unary Operators

Write a  Java Unary  Operators Program

PROGRAM: Java Unary Operators Program

/* Java Unary Operators Program */

class Main {
public static void main(String[] args) {

// declare variables
int a = 12, b = 12;
int result1, result2;

// original value
System.out.println(“Value of a: ” + a);

// increment operator
result1 = ++a;
System.out.println(“After increment: ” + result1);

System.out.println(“Value of b: ” + b);

// decrement operator
result2 = –b;
System.out.println(“After decrement: ” + result2);
}
}

6. Java Bitwise Operators

Write a  Java Bitwise Operators Program

PROGRAM: Java Bitwise Operators Program

/* Java Bitwise Operators Program */

Bitwise complement Operation of 35

35 = 00100011 (In Binary)

~ 00100011 
  ________
   11011100  = 220 (In decimal)

Other operators

Java instanceof Operator

The instanceof operator in Java is used to check whether an object belongs to a specific class or implements a specific interface. It returns true if the object is an instance of that class (or its subclass), otherwise false.

class Main {
public static void main(String[] args) {

String str = “Programiz”;
boolean result;

// checks if str is an instance of
// the String class
result = str instanceof String;
System.out.println(“Is str an object of String? ” + result);
}
}

Java Ternary Operator

The ternary operator in Java is a shorthand way of writing an if-else statement.
It uses the symbols ? : and evaluates a condition to return one of two values.

class Java {
public static void main(String[] args) {

int februaryDays = 29;
String result;

// ternary operator
result = (februaryDays == 28) ? “Not a leap year” : “Leap year”;
System.out.println(result);
}
}
