String
class StringDemo3
{
public static void main ( String[] args )
{
String str = new String( "Golf is a good walk spoiled." ); // create the original object
String sub = str.substring(8); //create a new object from the original
System.out.println( sub );
}
}
Many of the methods of String objects create other String objects.
For example,
the substring(int begin) method
creates a new String that contains a copy of
part of the data in the original string.
The example program uses this method.
The expression
str.substring(8)
creates a new String object.
That object contains its own data,
which are characters copied from the original string.
The original string is not changed.
The copy starts with character number 8 of the original string
and continues to the end.
Character numbering starts at zero, so
character number 8 in the original string is the first 'a'.
The substring of the original string is contained in a new String object.
A reference to that new string is assigned to the reference variable sub.
What characters are contained in the new object?
Remember that character numbering starts at zero.
