    Hey Man,

    The problem is that the system class is not found. The reason being the naming convention. You gotta follow the naming conventions. All the class names in java starts with Caps. So , your "system.out.print" should be "System.out.print".

    Also, your class name (password) should start with a Caps. Better use Password.

    Good Luck :-)

    Actually I found lot many changes. Please find the revised code. A suggestion for you is to develop your basic skills. The reason being the usage of the char variable in the program. Instead of using the variable list, you used the keyword char and thats the reason for the errors.

    public class Password {

    public static void main (String args[]) {

    char list[] = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V',' W','X','Y','Z','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s' ,'t','u','v','w','x','y','z','0','1','2','3','4','5','6','7','8','9','(',')','[',']','<','>','{','}','+','=','@','#','$','%','!','&','*','?'};

    for (int a=0; a<80; a++) {
    for (int b=0; b<80; b++) {
    for (int c=0; c<80; c++) {
    for (int d=0; d<80; d++) {
    for (int e=0; e<80;e++) {
    for (int f=0; f<80; f++) {
    for (int g=0; g<80; g++) {
    for (int h=0; h<80; h++) {


    System.out.print(list[a]);
    System.out.print(list[b]);
    System.out.print(list[c]);
    System.out.print(list[d]);
    System.out.print(list[e]);
    System.out.print(list[f]);
    System.out.print(list[g]);
    System.out.println(list[h]);
    }
    }
    }
    }
    }
    }
    }
    }
    }
    }
