As the title says, given a string, I would like to pad it (append) with n number of x character. Please see the below code. Is it possible to do that all in one String.format?
The commented line shows how to append n number of spaces; I would like to do the exact same thing with a custom character.
int paddingLength = (int) args.get(0);
String paddingItem = (String) args.get(1);
String temp = ((String) row.get(fieldName));
//temp = String.format("%-" + n + "s", s);
temp = String.format("%-" + paddingLength + "paddingItem", paddingItem + "temp", temp);
Example:
paddingLength: 5
paddingItem: "_"
temp = "test"
result: "test_____"
Another option is using StringBuilder. Example.
int n = 5;
char x = '_';
String temp = "test";
StringBuilder paddedWord = new StringBuilder(temp);
for(int i=0; i<n; i++)
paddedWord.append(x);
Just remember to cast your StringBuilder back to a String if you are using it elsewhere .toString()
