Please do the program in JAVA

Sorting file: lines in a new file must be in alphabetical order after sorting Small and capital letters are treated the same: A and a are the same letter; not case sensitive Describe algorithm in README.txt file, it can be drawing Searching: find word in the file Describe algorithm in README.txt file, it can be drawing. Estimate theoretically number of operations, depends of input n, in terms big-o notation Insert variable counter and calculate exact number of operations. Test your program with data, that gives you minimum, maximum, average number of operations. Provide input and output files for all cases. You can use any sorting method. What generalization of the problem can you offer to continue development of this problem? How can you apply solution of this problem in your life
