Collections: Strings
Python |
Java |
A string is a sequence
of 0 or more characters. Strings are instances of
the str class.
Strings are immutable objects. The len function returns the number of characters in a string. The subscript operator ([]) accesses a character at a given position. Example: aString = "Hello
world!" print(len(aString), aString[2])
Strings can be compared
using the standard comparison operators ==, <, etc. |

Strings are immutable objects. The length() method returns the number of characters in a
string. The charAt method accesses a character at a given position. Example: String aString
= "Hello world!" System.out.println(aString.length());
System.out.println(aString.charAt(2)); The String class includes many useful methods for searching, obtaining
substrings, and so forth. Strings should be
compared using the methods equals and compareTo. |
