string.isdigit() Parameters: isdigit() does not take any parameters Returns : 1.True- If all characters in the string are digits. A character is a digit if its general category type, provided by getType(codePoint), is DECIMAL_DIGIT_NUMBER. The Character.isDigit (char ch) java method determines if the specified character is a digit. That is if the general category type of a character, provided by Character.getType (ch), is DECIMAL_DIGIT_NUMBER, then the character is a digit.
