Java regex pattern

Is there any way of excluding this characters: - \ _ to this pattern? I need especifically this pattern and no other

Pattern pattern = 开发者_JAVA百科Pattern.compile("[\\p{P}\\p{Z}]");

Use character class subtraction:

Pattern.compile("[\\p{P}\\p{Z}&&[^-_\\\\]]");

Generally to exclude a character you prepend it with ^. for example to match any number of characters that do not containt character 'a' you write:

[^a]*
