public class stringtowords
{
public static void main(String args[])
{
String s="hello! my name@ is pragya";
String wo[]=s.split(" ");
for(String w:wo)
{
System.out.println(w);
}
String word;
for(int i=0;i<wo.length;i++)
{ word=wo[i].toLowerCase();

List<character> li=new ArrayList<character>();
for (char ch:word.toCharArray())
if(ch>='a' && ch<='z')
li.add(ch);
//for(char ch:li)
String ss=li.toString();
System.out.println(ss);

}
}
}

I'm trying toString() to convert it into String but it's not working.

As far as I know, you have to iterate over list items. Try

Java

public static void main(String arg[])
{
  List<Character> lc = new ArrayList<Character>();
  lc.add('p');
  lc.add('r');
  lc.add('a');
  lc.add('g');
  lc.add('y');
  lc.add('a');

  StringBuilder sb = new StringBuilder();

  for (Character c : lc)
    sb.append(c.charValue());

  String s = sb.toString();

  System.out.println(s);
}
