Hit count: 175
I have this code:
public static String SelectRandomFromTemplate(String template,int count) {
String[] split = template.split("|");
List<String> list=Arrays.asList(split);
Random r = new Random();
while (list.size()>count) {
list.remove(r.nextInt(list.size()));
}
return StringUtils.join(list, ", ");
}
I get this:
06-03 15:05:29.614: ERROR/AndroidRuntime(7737): java.lang.UnsupportedOperationException
06-03 15:05:29.614: ERROR/AndroidRuntime(7737): at java.util.AbstractList.remove(AbstractList.java:645)
How would be this the correct way? Java.15
