How to clear/empty Java Stringbuilder

I’m adding values to a string and then displaying it in a text view, but when I refresh the page it doesn’t clear the string first.
It just keeps adding to it.

Is there a way to clear a string builder in android?

What I have tried so far

StringBuilder sb = new StringBuilder();
sb.delete(0,sb.length());
for (String s : awayScores)
{
    sb.append(s);
    sb.append("\n");
}

StringBuilder sb2 = new StringBuilder();
sb2.delete(0,sb2.length());
for (String h : homeScores)
{
    sb2.append(h);
    sb2.append("\n");
}

 String awayeve = sb.toString();
 String homeeve = sb2.toString();

Log.v("home", "homeeve" + homeeve);
Log.v("home", "awayeve" + awayeve);

Answer 1

Try using sb.delete(0,sb.length());

EDIT:

StringBuilder sb2 = new StringBuilder();
sb2.delete(0,sb2.length());

In the code above, you are trying to delete contents of an empty StringBuilder.

This can’t be done.
