The substring(int index) Function
This function extracts all the characters from the index position till the end of the string. It returns a string, which is a
substring of the given string. The syntax is:
String <variable> = String_datatype_Variable.substring(int index);
Let us see the below example:

Write a program to extract a substring starting from index 8 in the string and display the
Program 10
result.
1 class substring

2 {
3 public static void main(String[] args)
4 {

5 String str= "India - New Delhi";

6 String seperate= str.substring(8);
7 System.out.println("The Extracted string is: " +seperate);
8 }

9 }

The output of the preceding program is as follows:
BlueJ: Terminal Window - Java

Options

The Extracted string is: New Delhi

The substring(int startindex, int endindex) Function
This function extracts all the characters from the index position ‘startindex’ till 1 less than the ‘endindex’. It always
returns a string, which is also a substring of the original string. The syntax is:

String <variable> = String_datatype_Variable.substring(int startindex, int endindex);
Let us see the below example:

Program 11 Write a program to extract a substring from index 8 to 11 in the string and display the result.

1 class substring
2 {
3 public static void main(String[] args)

4 {

5 String str= "India - New Delhi";
6 String removestr= str.substring(8,11);
7 System.out.println("The Extracted string is: " + removestr);

8 }
9 }
