In Java, we can easily find the square root of a number using the inbuilt function 'Math.sqrt()'. But sometimes during an interview, the interviewer may ask to write the code from scratch without using inbuilt functions. So in this article, we will discuss the different ways to find the...

Example: Java Program to Find Roots of a Quadratic Equationpublic class Main { public static void main(String[] args) { // value a, b, and c double a = 2.3, b = 4, c = 5.6; double root1, root2; // calculate the discriminant (b2 - 4ac) double discriminant = b * b - 4 *...
We can use a binary search to find the square root of a number without using the sqrt function. Since the range of the number is from 1 to 263, the root is between 1 and 231.5. So, the binary search algorithm needs about 16 iterations to get the square root: public boolean isPerfect...

In abidirectionalrelationship, each entity has a relationship field or property that refers to the other entity. Through the relationship field or property, an entity class’s code can access its related object. If an entity has a related field, the entity is said to “know” about its relat...

eyelids during capture, the captured data also contained some influence from eyelashes, which manifested itself as noise in those regions. As a result, the geometry of the eyelids was inaccurate and jittery, and this meant that we had to find a way to reconstruct the geometry in those regions...
