    Scanner sc=new Scanner(System.in);
    System. Out. Println ("how many marks did you get in this exam? "";
    //Enter your score information. Note that the score of type is decimal, so you can't use integer type. You can use floating point type

    //If the score is greater than or equal to 0 and the score is less than 60
    //Fail output
    if (chengji>=0&&chengji<60) {
      System. Out. Println ("you failed, why don't you work hard?";  
    }
    //If the score is 60 or more and the score is 80 or less
    //You passed the grade output
    else if(chengji>=60&&chengji<=80){

    else if (chengji>80&&chengji<=90) {

    }
    //If the score is greater than 90 and the score is less than or equal to 100
    //Your results are excellent
    else if (chengji>90&&chengji<=100) {
      System. Out. Println ("your score is super good, come to be a programmer! "";
    } 
    //Any of the above conditions are excluded. The input information is illegal
