Question

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 <input file> -f "<find-string>" -r "<replace-string> -o <output file>

*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 <find - string> in the input file <replace -string> 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.
