Syntax

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.

Example

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:
