operations

1)

class Demo{
    public static void main(String[] args){
        System.out.println(10/0.0);
    }
}

output:- infinity

in this expression we are dividing integer number(10) by (0.0) which is floating point number (double in java).

so (0.0) is a floating point number in java performs floating point division instead of integer division.

when we perform division operation in java if atleast one operand is floating point number then result is positive or negative infinity.

class Demo{
    public static void main(String[] args){
        System.out.println(-10/0.0);
    }
}

output:- -infinity.

in floating point arithmatic there is way to represent result infinity , -infinity and NaN.

2)

class Demo{
    public static void main(String[] args){
        System.out.println(0.0/0.0);
    }
}

output:- NaN.

in this expression we are dividing floating point number (double in java)by floating point number and the result is NaN.

NaN means not a number.

NaN is a special value in floating-point arithmetic that represents an undefined or unrepresentable value.

3)

class Demo{
    public static void main(String[] args){
        System.out.println(10/0);
    }
}

output:- airthmatic Exception

in this expression both operands are integer number so integer division operation performs.

in java does not allow to perform division by zero so it throws an airthmatic Exception in runtime.

in integral arithmatic (byte ,short, int ,long) there is no way to represent infinity hence we will get Airthmatic Exception.

class Demo{
    public static void main(String[] args){
        System.out.println(0/0);
    }
}

output:- Airthmatic Exception
