CharAt() in Java

In this section, we will discuss about charAt() method of String class and how it is used. It comes in java.lang.String package. charAt() method returns a character value for the character at the given position of the string. Index value of charAt() method starts from 0 and ends at length-1 of the String. It throws IndexOutOfBoundsException if value of index is negative or greater than the length of the String.

Syntax:

public char charAt(int index)

In the following example we have used charAt() method to find the character at the 4th position of the string and retrieve it.

Example of charAt() in Java:

import java.io.*;
class CharAt{
public static void main(String[] args){
try{
BufferedReader object=
new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the String");
String s=object.readLine();
int len=s.length();
System.out.println(len);
char char1=s.charAt(4);
System.out.println(char1);
}
catch(Exception e){}
}
}

Output:

C:\java_work>java CharAt

Enter the String
