java find and replace code pls help me We write code that can find and replace in a given text file. The code you write should take the parameters as command line arguments:

java FindReplace -i -f "" -r " -o

*question mark(?) can be used instead of any character.

"?al" string an be sal ,kal,val

*In addition, a certain set of characters can be given in brackets.(

"kng[a,b,f,d,s]ne" string an be kngane,hngbne,kangfne,kangdne,kangsne

So, all you have to do is match all strings that match  in the input file  and output (output the entire contents of the input file) output file. The input file needs to remain unchanged. Input and output files will be a text file. Both strings will be separated by a double quotation mark (") character. To change these special characters in Java you will need to enter an escape character (backslash) like

examples=

java FindReplace -i input.txt -f "sam?jack[3,4,5]" -r "samjack49" -o output.txt

java FindReplace -i doc -f "sam-jack fou?rth nine fifth" -r "sam jack 49 50 " -o doc2

java FindReplace -i input -o output -r "-f" -f "-r"

[replace input -r with -f and write result to output file]

java FindReplace -o out -i inp -f "\[\]" -r "{}"

[replace input [] with {} and write result to output file]

java FindReplace -i input.txt -o output.txt -f "\[?\]" -r "[a]"

[bracketed strings with single characters in it. Replace with [a]]

java FindReplace -i input -o output -f "\?" -r "question mark"

java FindReplace -o out -i input -f "\"" -r " ' "

java FindReplace -i inp -f "sam" -r "jack"

***PLS regex mechanism will not be used.
