JAVA, arrays

How this code part should be edited to show numbers form 0-10 included not only form 0-9?

char[][] arr = new char[11][11]; /ecessary to keep

for(int i=0;i

{

for(int j=0;j

{

if(i==0)

arr[i][j] = (char)(j + '0');

else if(j==0)

arr[i][j] = (char)(i + '0');

else

arr[i][j] = '~'; /ecessary to keep

}

}

So the idea, where are stars on picture to be numbers of array row and column including 0 point as corner
