    Question how to count and print asterisk.

     int ct=0;
        BufferedReader input=new BufferedReader(new InputStreamReader(System.in));
        do {
     
     
        System.out.println("Enter Grade:");
        int grade=0;
        grade = Integer.parseInt(input.readLine());
     
        ct++;
     
    // start
     
        if(grade==0 || grade==1 || grade==2 || grade==3 || grade==4 || grade==5 || grade==6 || grade==7 || grade==8 || grade==9 || grade==10)
        { // missing statement and agruments} 
        else if(grade==11 || grade==12 || grade==13 || grade==14 || grade==15 || grade==16 || grade==17 || grade==18 || grade==19 || grade==20)
        {}
        else if(grade==21 || grade==22 || grade==23 || grade==24 || grade==25 || grade==26 || grade==27 || grade==28 || grade==29 || grade==30)
        {}
        else if(grade==31 || grade==32 || grade==33 || grade==34 || grade==35 || grade==36 || grade==37 || grade==38 || grade==39 || grade==40)
        {}
        else if(grade==41 || grade==42 || grade==43 || grade==44 || grade==45 || grade==46 || grade==47 || grade==48 || grade==49 || grade==50)
        {}
        else if(grade==51 || grade==52 || grade==53 || grade==54 || grade==55 || grade==56 || grade==57 || grade==58 || grade==59 || grade==60)
        {}
        else if(grade==61 || grade==62 || grade==63 || grade==64 || grade==65 || grade==66 || grade==67 || grade==68 || grade==69 || grade==70)
        {}
        else if(grade==71 || grade==72 || grade==73 || grade==74 || grade==75 || grade==76 || grade==77 || grade==78 || grade==79 || grade==80)
        {}
        else if(grade==81 || grade==82 || grade==83 || grade==84 || grade==85 || grade==86 || grade==87 || grade==88 || grade==89 || grade==90)
        {}
        else if(grade==91 || grade==92 || grade==93 || grade==94 || grade==95 || grade==96 || grade==97 || grade==98 || grade==99 || grade==100)
        {}
        else { System.out.println("Error only 0-100!Going back to Menu"); menus(); } 
     
    //end of else if conditions
     
     
            }  while(ct<=9);// do bracket;
     
     
       System.out.println("00-10"+asterisk+"");
       System.out.println("11-20"+asterisk2+"");
       System.out.println("21-30"+asterisk3+"");
       System.out.println("41-50"+asterisk4+""); // display grades and count using asterisk(*)
       System.out.println("61-70"+asterisk5+"");
       System.out.println("71-80"+asterisk6+"");
       System.out.println("81-90"+asterisk7+"");
       System.out.println("91-100"+asterisk8+"");
    }


    My problem is that i don't know how to count it after the input of grades and print asterisk on each condition.

    I'm really not sure what your question is, but you might want to look into for loops?

    how to count it
    What is the "it" that is being counted?
    Does the program's output show the problem? If so, copy the output here and add some comments to it that shows what is wrong with the output and show what the output should be.

    Are you trying to count the grade values in specific ranges?
    You can detect ranges by using the >= and <= operators instead of using the == operator for all the values.
    If you don't understand my answer, don't ignore it, ask a question.

    Default Re: how to count and print asterisk.

    If the *s are being printed, look at using the print() method inside a loop to print *s all on one line.
    Then use the println() method to move to the next line.

    You can't. Use the int value to control the loop with the print("*") inside it.

    You would need a special loop at the place where you want to print the *s.
    You'd probably want to write a method to do it that you would pass the number of *s to be printed as its arg.

    The printf() method has formatting capabilities that would help you have spaces to make the columns align.

    Please explain what you mean by "align".
    what do you want the output to look like?
    Put the output in code tags to preserve its formatting.

    What does the output from the program look like? How is it different from what you want?

    The posted code is poorly formatted. The ending }s should not be HIDDEN at the end of a statement.
    All the for statements that are at the same logic level should start in the same column.
    The println() statements should be indented.
    If you don't understand my answer, don't ignore it, ask a question.

    Default Re: how to count and print asterisk.

    Your logic will have to print the rows starting at the top, build each row column by column, inserting an * when a column should have an *. There would be as many rows as the tallest column to be built.
    If you don't understand my answer, don't ignore it, ask a question.
