Java.lang.StringBuffer.subSequence() Method
Description
The java.lang.StringBuffer.subSequence() method returns a new character sequence that is a subsequence of this sequence with start as starting index and end as ending index.
Declaration
Following is the declaration for java.lang.StringBuffer.subSequence() method
public CharSequence subSequence(int start, int end)
Parameters
start − This is the start index, inclusive.
end − This is the end index, exclusive.
Return Value
This method returns the specified subsequence.
Exception
IndexOutOfBoundsException − if start or end are negative, if end is greater than length(), or if start is greater than end.
Example
The following example shows the usage of java.lang.StringBuffer.subSequence() method.
package com.tutorialspoint; import java.lang.*; public class StringBufferDemo { public static void main(String[] args) { StringBuffer buff = new StringBuffer("admininstrator"); System.out.println("buffer = " + buff); CharSequence cSeq; // returns the specified subSequence cSeq = buff.subSequence(0,5); // print the subsequence System.out.println("subSequence = " + cSeq); } }
Let us compile and run the above program, this will produce the following result −
buffer = admininstrator subSequence = admin
