There are two possible approaches for this.

1. Either you create an internal representation of the output (like a two-dimensional character array) in which you draw the graphics.

   When the image is done, you print the whole array.

2. You use escape sequences (which are specific to your terminal) to move the cursor to a certain place to draw characters.

   In your case, you should clear the terminal once and then move the cursor for each asterisk.

[EDIT] As for #1:

char[][] screen = new char[20][]; // 20 lines
for(int i=0;i<screen.length; i++) screen[i] = new char[80]; // 80 columns

Now you can draw something with screen[y][x] = '*'

To print:

for(int i=0;i<screen.length; i++) System.out.print(new String(screen[i]));
System.out.println();
