2. Get Unicode Code Point at Index

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

Sample Solution:

Java Code:

// Define a public class named Exercise2.
public class Exercise2 {
    // Define the main method.
    public static void main(String[] args) {
  
        // Declare and initialize a string variable "str" with the value "w3resource.com".
        String str = "w3resource.com";
        // Print the original string.
        System.out.println("Original String : " + str);
        
        // Retrieve the Unicode code point at index 1 in the string.
        int val1 = str.codePointAt(1);
    
        // Retrieve the Unicode code point at index 9 in the string.
        int val2 = str.codePointAt(9);
        
        // Print the Unicode code point representing the character at index 1 in the string.
        System.out.println("Character(unicode point) = " + val1);
        // Print the Unicode code point representing the character at index 9 in the string.
        System.out.println("Character(unicode point) = " + val2);
    }
}

Sample Output:

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

• Write a Java program to extract and display the Unicode code point of the character at a user-specified index.
• Write a Java program that iterates over a string and prints the Unicode code point for every character at an even index.
• Write a Java program to compare Unicode code points at two different user-input indices and display their difference.
• Write a Java program to validate an index before printing the Unicode code point of the character at that position.
