How can I stack up the number patterns with while loop in java? -

dear professionals! i'm super beginner of programming java. i'm learning basic stuff in school. while i'm doing homework, i'm stuck in 1 problem.

the question using nested loops make stack-up number pattern:

1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 1 2 3 4 5 6 1 2 3 4 5 6 7 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 8 9 10 

i can use while loop (because haven't learned or loops yet), , outer loop body should execute 10 times. can use print , println making pattern.

i tried many different methods while loop, can't figure out.

please, please give me hint.

this code i'm working on far:

class c4h8 {     public static void main(string[] args)     {         int i, j;          = 1;         while(i <= 10)         {             j = 1;             while (j <= 10)             {                  system.out.print(j);                 j++;              }               system.out.println();             i++;          }      } } 

but displays:

12345678910 12345678910 12345678910 12345678910 12345678910 12345678910 12345678910 12345678910 12345678910 12345678910 

my question may silly one, i'm struggling because mentioned, i'm super beginner.. please me, can learn , move on!

thank much!

use following: need limit variable j variable i achieve output

class c4h8 {     public static void main(string[] args)     {         int i, j;          = 1;         while(i <= 10)         {             j = 1;             while (j <= i) // limit variable j              {                  system.out.print(j+" ");                 j++;              }              system.out.println();             i++;          }     } }
