.subSequence()

.subSquence() is a String method that returns a new character sequence that is a substring of a given string.

str.subSequence(int startIndex, int endIndex)

The .subSequence() method will return a substring of the str string from startIndex to endIndex - 1.

The .subSquence() method takes two parameters:

• startIndex - the starting index (inclusive).
• endIndex - the ending index (exclusive).

Both parameters must be integers.

The following example will return a substring of the str string.

  class Main {
    public static void main(String[] args) {
      String str = "Java Programming";

      System.out.println(str.subSequence(0, 4));
    }
}

This will print:
