在Java中循环

Question

Consider my codes are below :

int number = 0;
while ((number >=0.5) && (number <= 27.5)) {
    if (number % 1.25 == 0) {
        number +=0.75;
    } else {
        number++;
    }
}
}

my question is what is the problem in the codes above? and if i want to print out the result, the variable number should has the following number of 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 during the process of looping. how do i do that?

Answer 1

It will never enter the loop because 0 is not >= 0.5

It's not at all clear why you are dealing with quantities such as 0.5, 1.25, 27.5, what exactly are you trying to accomplish? To print the numbers 6 to 28 doesn't need any of those fractional values.

Answer 2

You need to include the purpose of your code for others to figure out what is the problem with it.

The issues I see are:

Your while loop would never start because the initial assignment for "number" is out of range.

Also, I see you increment "number" by 1, so your "% 1.25" will never execute.

If you just need to loop from 6 to 28 using the code similar to yours, should be something like this:

int number = 6;
while (number < 29) {
  System.out.println(number);
  number++;
}

Answer 3

Try something like ...

int number = 5;
while ((number >=5) && (number <= 27.5)) {
  System.out.println(""+number++);
}
