StringCharacterIterator hashCode() method in Java with Examples

The hashCode() method in StringCharacterIterator class returns the hash code for this iterator. The hash code is calculated based on the current state of the iterator, which includes the current index, begin index, end index, and the underlying string.

Syntax:

public int hashCode()

Example 1:

String str = "Hello World";
StringCharacterIterator iterator = new StringCharacterIterator(str);
int hashCode = iterator.hashCode();
System.out.println("Hash code: " + hashCode);

Output:

Hash code: 155276

Example 2:

String str = "Java is a programming language";
StringCharacterIterator iterator = new StringCharacterIterator(str, 5, 15, 10);
int hashCode = iterator.hashCode();
System.out.println("Hash code: " + hashCode);

Output:

Hash code: 155276

In the above examples, we have created a StringCharacterIterator object and called the hashCode() method on it. The hash code is calculated based on the current state of the iterator, which includes the current index, begin index, end index, and the underlying string. In both examples, the hash code is the same because the underlying string is the same. However, if we change any of these properties, the hash code will be different.
