Sum of 10 numbers Display the sum of numbers from 1 to 10 line by line (there should be 10 lines):

1 1+2=3 1+2+3=6 1+2+3+4=10 ...

Example output:

 1 3 6 10

Here is a sample code, I do not know what to do next ...

 public static void main(String[] args) { for(int a = 1; a <= 10; a++){ System.out.println(a); } }

You just have to memorize the amount and add the following number to it each time:

 public static void main(String[] args) { Integer sum = 0; for(int i = 1; i <= 10; i++) { sum = sum + i; System.out.println(sum); } }

  • Thank you very much. I also thought that the current put this variable sum in the for block and with each cycle the initial value was returned - user212022
  • ter will know - user212022
  • @ user212022 if you were given the correct answer, tick it as correct for those who later come across this question. - Denis
