How to print out 10 rows of 10 characters (or strings) in java non-tediously -

i'm going through beginners exercise writing small program in java. task print out (i.e. find algorithm) following output

xooooooooo xxoooooooo xxxooooooo xxxxoooooo xxxxxooooo xxxxxxoooo xxxxxxxooo xxxxxxxxoo xxxxxxxxxo xxxxxxxxxx 

i have figured out how code wrote seems repetitive , tedious. how can shorten code? there must easier way achieve this?

here code of now;

package helloworld;  public class helloworld {  public static void main(string[] args)  {     // output       // algorithm 1      boolean ft = true;      string s = new string();     for(int = 0; < 10; i++)     {         s  += "x";         for(int j = 0; j < 9; j++)         {             if(i == 0)             {                  s += "o";             }              if(i == 1)             {                  if(ft == true)                 {                     s+="x";                     ft = false;                 }                 if(j == 8)                 {                     continue;                 }                 s += "o";             }              if(i == 2)             {                  if(ft == true)                 {                     s+= "xx";                     ft = false;                  }                  if(j == 7)                 {                      break;                 }                 s += "o";              }              if(i == 3)             {                  if(ft == true)                 {                     s+= "xxx";                     ft = false;                  }                  if(j == 6)                 {                      break;                 }                 s += "o";             }              if( == 4)             {                 if(ft == true)                 {                     s+= "xxxx";                     ft = false;                  }                  if(j == 5)                 {                      break;                 }                 s += "o";             }              if( == 5)             {                 if(ft == true)                 {                     s+= "xxxxx";                     ft = false;                  }                  if(j == 4)                 {                      break;                 }                 s += "o";             }              if( == 6)             {                 if(ft == true)                 {                     s+= "xxxxxx";                     ft = false;                  }                  if(j == 3)                 {                      break;                 }                 s += "o";             }              if( == 7)             {                 if(ft == true)                 {                     s+= "xxxxxxx";                     ft = false;                  }                  if(j == 2)                 {                      break;                 }                 s += "o";             }              if( == 8)             {                 if(ft == true)                 {                     s+= "xxxxxxxx";                     ft = false;                  }                  if(j == 1)                 {                      break;                 }                 s += "o";             }              if( == 9)             {                 if(ft == true)                 {                     s+= "xxxxxxxxx";                     ft = false;                  }                  if(j == 0)                 {                      break;                 }                 s += "o";             }           }         system.out.println(s);         s = "";         ft = true;      } }  } 

just use 2 nested loops:

string s; for( int = 0; < 10; i++) {     s = "";     for( int j = 0; j <= i; j++)         s+= "x";     for( int j = i+1; j < 10; j++)         s+= "o";     system.out.println(s); }
