Java String subSequence() method

This method returns a new character sequence i.e. subsequence of current sequence

Syntax:

public CharSequence subSequence(int beginIndex, int endIndex)

Parameter:

beginIndex ? begin index, inclusive.

endIndex ? end index, exclusive.

Return: specified subsequnce

Throws:

It throws IndexOutOfBoundsException if begin or end index is negative , if end is greater than length(), or if start is greater than end.

Java String subSequence() Example 1

public class JavaStringSubSequenceEx1
{
      public static void main(String[] args)
      {
            String s1 = "A subSequence Example.";
            CharSequence cs = s1.subSequence(2, 13);
            System.out.println();
            System.out.println(cs);
        System.out.println();
      }
}

Output:

subsequence

Java String subSequence() Example 2

public class JavaStringSubSequenceEx2
{
   public static void main(String args[])
   {
      String Str = new String("Welcome to tutorialandexample.com");
      System.out.print("Return Value :" );
      System.out.println(Str.subSequence(0, 10) );
      System.out.print("Return Value :" );
     System.out.println(Str.subSequence(10, 29) );
   }
}

Output:

Return Value :Welcome to
Return Value : tutorialandexample

Java String subSequence() method Example 3

import java.lang.Math;
public class JavaStringSubSequenceEx3{
    // driver code
    public static void main(String args[])
    {
        String Str = "Welcome to tutorialandexample";
        // throws an error as index is negative
        System.out.print("Returns: ");
        System.out.println(Str.subSequence(-1, 7));
    }
}

Output:

Returns: Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -1
       at java.lang.String.substring(String.java:1960)
       at java.lang.String.subSequence(String.java:2003)
       at JavaStringSubSequenceEx3.main(JavaStringSubSequenceEx3.java:13)

Java String subSequence() Example 4

public class JavaStringSubSequenceEx4
{
   public static void main(String args[]) {
      String Str = new String("Welcome to Tutorialandexample.com");
          System.out.println(Str.subSequence(11, 29) );
   }
}

Output:

Tutorialandexample
