Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.

Is that correct?
This is question 5 on the same chapter 9
Q5. According to legend, the monks in a remote mountain monastery knew how to predict when the world would end. They had a set of three diamond needles. Stacked on the first diamond needle were 5 gold disks of decreasing size. The monks moved one disk to another needle each hour subject to the following rules. (CO01) • Only one disk could be moved at a time. • A Larger disk must never be stacked above a smaller one. • One and One auxiliary needle could be used for the intermediate storage of disks. The legend said that when all 5 disks had been transferred to the destination needle, the stars would be extinguished and the world would end.Solve the above problem using recursion and draw a step by step procedure till the disks are transferred from source to destination.
