I wan't to add integers 1 to 30. How can I do that in java.
I tried using for and while loop but failed to add the integers.
I only get 1,2,3 etc.But I wan't to add 1+2+3 etc.
It has to be
0 + 1 =1
1 + 2 =3
3 + 3 =6
6 + 4 =10
10 + 5 =15
15 + 6 =21 and so on
upto 30.
Please help me or tell me the other way I can do it in Java. Correct me if I am wrong.

First you can try killing a chicken with a bull's knife by using OOP, ie classes.

Thanks Peter Tran,
I tried the coding. It's exactly what I was looking for but was not able to do the way you did it coz I was not using your first println statement:
Thanks again.
