This is my question.

Develop body of the following method public static void readWrite(String srcFileName, String dstFileName, String oldStr, String newStr) { } The method copies the content of thesrcFileNametodstFileNameline by line, and changes all occurance of theoldStringtonewStris thedstFileName. For example if the method is called by following parameters readWrite ("in.txt", "out.txt", " is ", " was "); // Note the the space before and after the words. if the content of thein.txtfile is this is a quiz, and this is an easy quiz. then the content of theout. txtwill be this was a quiz, and this was an easy quiz.OUTAWN import java. io.
