Java String Exercises: Get the character (Unicode code point) at the given index within the String

Java String: Exercise-2 with Solution

Write a Java program to get the character (Unicode code point) at the given index within the String.

Sample Solution:

Java Code:

public class Exercise2 {

   public static void main(String[] args) {
  
    String str = "w3resource.com";
    System.out.println("Original String : " + str);
        
    // codepoint at index 1
    int val1 = str.codePointAt(1);
    
    // codepoint at index 9
    int val2 = str.codePointAt(9);
        
    // prints character at index1 in string
    System.out.println("Character(unicode point) = " + val1);
    // prints character at index9 in string
    System.out.println("Character(unicode point) = " + val2);
  }
}

Sample Output:

Original String : w3resource.com                                                                              
Character(unicode point) = 51                                                                                 
Character(unicode point) = 101
