The key difference between a float and double in Java is that a double can represent much larger numbers than a float. Both data types represent numbers with decimals, but a float is 32 bits in size while a double is 64 bits. A double is twice the size of a float — thus the term...
float is a 32 bit floating point data type with low precision whereas double is a 64 bit floating point data type with high precision
public double divide(double a, double b) { if (b == 0) { throw new ArithmeticException("Divider cannot be equal to zero!"); } return a / b; } As you can see, we have used ArithmeticException with perfectly fits our needs. We can pass a single String constructor parameter which is...
1 == ‘1’ The result of this answer is true because when we compare two values using double equal then it comapares only value but 1 === ‘1’ this gives us false because this time not only checkes the value but its data type also. Siddharth Gajbhiye 5y 2 == and === is ...
