How do you calculate roots in Java?

Java program to find the roots of a quadratic equation

1. Calculate the determinant value (b*b)-(4*a*c).
2. If determinant is greater than 0 roots are [-b +squareroot(determinant)]/2*a and [-b -squareroot(determinant)]/2*a.
3. If determinant is equal to 0 root value is (-b+Math.sqrt(d))/(2*a)

What is switch in JavaScript?

The switch statement is a part of JavaScript’s “Conditional” Statements, which are used to perform different actions based on different conditions. Use switch to select one of many blocks of code to be executed. This is the perfect solution for long, nested if/else statements.
