[java] Adding whitespace in Java

There is a class trim() to remove white spaces, how about adding/padding?

Note: " " is not the solution.

If you have an Instance of the EditText available at the point in your code where you want add whitespace, then this code below will work. There may be some things to consider, for example the code below may trigger any TextWatcher you have set to this EditText, idk for sure, just saying, but this will work when trying to append blank space like this: " ", hasn't worked.

messageInputBox.dispatchKeyEvent(new KeyEvent(0, 0, 0, KeyEvent.KEYCODE_SPACE, 0, 0, 0, 0,
                        KeyEvent.KEYCODE_ENDCALL));

String text = "text";
text += new String(" ");

Use the StringUtils class, it also includes null check

StringUtils.leftPad(String str, int size)
StringUtils.rightPad(String str, int size)

There's a few approaches for this:

1. Create a char array then use Arrays.fill, and finally convert to a String
2. Iterate through a loop adding a space each time
3. Use String.format
