// Java program to print all the permutations
// of the given string
public class GFG {
 
    // Function to print all the permutations of str
    static void printPermutn(String str, String ans)
    {
 
        // If string is empty
        if (str.length() == 0) {
            System.out.print(ans + " ");
            return;
        }
 
        for (int i = 0; i < str.length(); i++) {
 
            // ith character of str
            char ch = str.charAt(i);
 
            // Rest of the string after excluding
            // the ith character
            String ros = str.substring(0, i) +
                         str.substring(i + 1);
 
            // Recursive call
            printPermutn(ros, ans + ch);
        }
    }
 
    // Driver code
    public static void main(String[] args)
    {
        String s = "abb";
        printPermutn(s, "");
    }
