Hi

I had a look at the class String, if there exist such methods. Till now I did not get a usefull idea. Once I thought, maybe you could the method:

public char[] toCharArray()

Then you have to parse an array. Probably there might be for each test one loop.

example:

for (int i = 0; i<array.length; i++){
if(array[i] == ...;
...
}

if (str.matches("(?=.*\\p{Upper})(?=.*\\p{Digit}).*\\p{Punct}.*"))
