	{
		PatternSplitAsStreamExample2 ps=new PatternSplitAsStreamExample2();
		Pattern p=Pattern.compile("[* & # $ !]+\\S");
		String s="javat*po int123@gmail.com";
		System.out.println(s + " -  [" + p.splitAsStream(s)
       		 .collect(Collectors.joining("")) + "]");

public class PatternSplitAsStreamExample3 {
	private void test(Pattern pattern, String s) {
	    System.out.println(s + "-[" + pattern.splitAsStream(s)
	            .collect(Collectors.joining("!")) + "]");
	}
	public static void main(String args[])
	{
		PatternSplitAsStreamExample3 ps=new PatternSplitAsStreamExample3();
		Pattern p=Pattern.compile("\\d+");
		ps.test(p,"aa1bb3cc4dd4ee");
		ps.test(p, "a5b5c5d5");
	}
}
