Returns the total number of characters included in the String as an integer number.
People are often confused by the use of length() to get the size of a String and length to get the size of an array. Notice the absence of the parentheses when working with arrays.
String str1 = "CCCP"; String str2 = "Rabbit"; int l1 = str1.length(); int l2 = str2.length(); println(l1 + ":" + l2); // Prints "4:6"
