public class MyClass { 
    static String remove_chars(String s, String chars) { 
        int i = 0, internal_i = 0, len = s.length(); 
        char arr[] = s.toCharArray(); 
         
        while (i != len) { 
            char ch = arr[i]; 
 
            if (chars.indexOf(ch) == -1) { 
                arr[internal_i] = arr[i]; 
                 
                internal_i++; 
            }
            i++; 
        }  
        s = new String(arr); 
         
        return s.substring(0, internal_i); 
    } 
       
    public static void main(String args[]) {
        String first = "java programming language"; 
        String second = "rogy"; 
         
        System.out.println(remove_chars(second, first)); 
    } 
}
