To get the sequence 1, 3, 6, 10, 15 … try the following: class Sums { public static void main(String[] args) { int sum = 0; // Use zero not oh. for (int i = 1; i <= 100; ++i) { sum += i; System.out.println(sum); } } } Of course, remember that the source file must be called "Sums.java". Then at the command line type javac Sums.java java Sums Adapt to your IDE as required.

class Program { public static void main(String[] args) { int sum=O; for(int x = 1; x <=100; x++) { sum = sum + x System.out.println("sum"); } } }

If, your want to print series 1,3,6,10,15,.... then use public class Program { public static void main(String[] args) { int i,s=1; for(i=1;i<=100;i++,s++) { System.out.println(i); i+=s; } } }

write i<=100 instead of writing i<101

class Program { public static void main(String[] args) { int sum=0; for(int x = 1; x <=100; x++) { sum+= x; System.out.println("sum= "+sum); } } } /* output: sum= 1 sum= 3 sum = 6 sum= 10 .... */

public static void main(String[] args) { for(int x = 1; x <101; x++) { System.out.println("x"); } } You could just simply print out 'x' , because 'x' itself will constantly be added by '1' due to the for loop anyway. Try it and you will know what I mean.

If you just want the numbers 1 to 100 printed out, use this: public class Test { public static void main(String[] args) { for(int i = 1; i <= 100; i++) { System.out.println("i is: " + i); } } } Then again though, if you want to print 1, 3, 6, 10, 15 etc. this isn't what you want.
