(a) Each JVM frame has a local variable area made up of 4-byte slots. Consider the Java method findRoots for solving quadratic equations, and explain which local variable will be stored in each slot. public class Quadratic { private double firstRoot; private double secondRoot; public int findRoots (double a, double b, double c){ double sqrt Math.sqrt((b * b)-(4 * a * c)); firstRoot (-b + sqrt) / (2 * a); secondRoot (-b - sqrt) / (2 * a); return 0; } = } [5 marks]
