How to write a fixed-point program in java?

Fixed-point method Problem 1. (15 points) Let f(). To solve f(x) 0, the following fixed- point problems are proposed. Write a fixed-point program to show which methods work appropriate. Use f(p)0.01 as a measure of error in the iteration. Output all of the iterations. Use Fixed-point theorem to explain why (a) =-(r' + 1), Po = 0.5 (b)= (c) x=y2--, po = 0.5 (1) x=-V1-2
