java - Can someone explain to me why this nested loop function print this way? -

so here code runs:

public static void main(string[] args)  {     (int i=1; i<=6; i++)      {         (int j=1; j<=i; j++)          system.out.print("*");         system.out.print("-");     } } 

why print

*-**-***-****-*****-******-

instead of

* _ ** __ *** ___ **** ____ *****_____******______

system.out.print("-"); not inside inner loop. therefore it's printed once each iteration of outer loop.

this becomes clearer when indent code :

for (int i=1; i<=6; i++)  {     (int j=1; j<=i; j++)          system.out.print("*");     system.out.print("-"); } 

even if inside inner loop (by adding curly braces), you'd still not output expected, since you'll 1 - after each *.

in order output expected, need 2 inner loops :

for (int i=1; i<=6; i++)  {     (int j=1; j<=i; j++)          system.out.print("*");     (int j=1; j<=i; j++)          system.out.print("-"); }
