        { 

            System.out.println(s);

        } 
          for (int j = 0; j < len; j++) 
        {

            generate(arr, i - 1, appended, len); 
        } 

        return; 
    } 


    static void crack(char[] arr, int len) 
    { 

        for (int i = 1; i <= len; i++) 
        { 
            generate(arr, i, "", len); 
        } 
    } 


    public static void main(String[] args) 
    { 
        char arr[] = {'a', 'b', 'c'}; 
        int len = arr.length; 
        crack(arr, len); 
    } 

}

If you want to save the outputs on the console to a file you can simply redirect System.out like explained in this question.

So all the outputs on the console (that are printed using System.out) are not printed on the console, but in a file.
