Requirements

Write code to Checks if the String contains any character in the given set of characters. 

containsAny(null, *)                = false
containsAny("", *)                  = false
containsAny(*, null)                = false
containsAny(*, [])                  = false
containsAny("zzabyycdxx",['z','a']) = true
containsAny("zzabyycdxx",['b','y']) = true
containsAny("aba", ['z'])           = false

Hint

Use nested for loop

Demo

public class Main{
    public static void main(String[] argv){
        String str = "book2s.com";
        char[] searchChars = new char[]{'b','o','o','k','2','s','.','c','o','m','a','1',};
        System.out.println(containsAny(str,searchChars));
    }/*from  w  w  w  .ja  v  a 2s. co  m*/
