Parameter Input :

DataType Parameter Description
int index index to the char values

Method Returns :

The codePointAt(int index) method simply returns ode point value of the character at the index.

Compatibility Version :

Requires Java 1.5 and up

Java Code Example :

This java example source code demonstrates the use of codePointAt(int index) method of StringBuffer class. Initially the code assigns a string “java-tutorial” as initial contents of the string buffer. Then we use the codePointAt of the StringBuffer at index 3.


 * This example source code demonstrates the use of codePointAt(int index) 
 * method of StringBuffer class

public class StringBufferCodePointAt {

	public static void main(String[] args) {

		// initialize the StringBuffer object
		StringBuffer sb = new StringBuffer("java-tutorial");
		System.out.println("Contents of buffer:" + sb);

		// get the codepointat on index 3
		int index = 3;
		System.out.println("CodepointAt index " + index + " is "
				+ sb.codePointAt(index));


Sample Output :

Running the codePointAt(int index) method example source code of StringBuffer class will give you the following output
