Design a class to overload a function series$()$ as follows

$[7]$

$($i$)$ double series$($double $n)$ with one double argument and returns the sum of the series

Sum $=\frac{1}{1}+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+$dotsdotsdotsdotsdots$\frac{1}{n}$

$($ii$)$ double series $($double a$,$ double $n)$ with two double arguments and returns the sum of the series.

Sum $=\frac{1}{a^2}+\frac{4}{a^5}+\frac{7}{a^8}+\frac{10}{a^{11}}$ n terms Solve using java
