Hi All,

Why the following code giving UnsupportedOperationException at Line1 when running the program? Can't we able to remove a value from list, which is converted from an array? please explain?
import java.util.*; class RemList { public static void main(String [] args) { String [] sa = {"one", "two", "three", "four"}; List <String> st=Arrays.asList(sa); System.out.print(st); st.remove(2); // line 1 System.out.print(st+ "\n"); for(String s : sa) { System.out.print(s+" "); } } }
