Permutations of a string

Question

public class Permute {
    public static void main(String[] args) throws IOException {
        System.out.println(\"Enter a string\");
        BufferedReader bufReader =         


        

Answer 1

Replace two lines in the for loop with following:

 String partString = input.substring(0, i) + input.substring(i + 1);
 shuffle(dummy + input.charAt(i), partString);

Since this looks like your homework I will let you figure out. If not, will post explanation after a bit ( got to get back to my day job ;) )
