Print variable from right to left in java

Question

I want to print variable from right. This is my code to show '#' symbol:

static void printNumberSignVertical(int n, boolean newLine){
    for(int i = 0; i < n; i++){
        System.out.print('#');
    }
    if(newLine){
        System.out.println("");
    }
}

and then this is my output :

I want to print symbol '#' from the right. How can i make that symbol printed from right to left?

this is my representation how the print order is desired :

it starts from 1st one.

What do you mean right-to-left? You want it to print from the right side of the screen instead? — Zephyr, Aug 08 '18 at 00:32
yes, i want to print symbol '#' from the right side first @Zephyr — dazzle, Aug 08 '18 at 00:35
see https://docs.oracle.com/javase/tutorial/2d/text/textlayoutbidirectionaltext.html — Scary Wombat, Aug 08 '18 at 00:35
@ScaryWombat - It looks like the OP is using the console. Would the AWT article apply? (I'm not familiar with AWT, but I believe it is all GUI-based, no?) — Zephyr, Aug 08 '18 at 00:36
@dazzle - I'm not sure that can be done with `System.out` as the text direction depends on the OS and console implementation. You might need to do some calculations to determine the width of the display and go from there. — Zephyr, Aug 08 '18 at 00:37
@dazzle your requirement is not clear enough. Could you please add your current and expected outcome examples. — Vikasdeep Singh, Aug 08 '18 at 00:40
i have edited my question and give an example about my representation ouput @VicJordan — dazzle, Aug 08 '18 at 01:25
@dazzle sadly I can not see images you have posted. Could you please post links from other site or instead of image provide textual information? — Vikasdeep Singh, Aug 08 '18 at 01:28

Assuming the terminal is exactly 80 characters wide, you could use formatted io to indent the String (#) (and a newline). Like,

System.out.printf("%80s%n", "#");

This still has to draw left to right, but it will align as I think you wanted.

@dazzle Was there something in my answer that made you think I did not understand that from your question? – Elliott Frisch Aug 08 '18 at 01:28

for(int i = 79; i > -1; i--){
if(i>=n){
System.out.print(" ");
}else{
System.out.print('#');
     }
