Java: Get the character (Unicode code point) before the specified index within the String

Java String: Exercise-3 with Solution

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

Sample Solution:

Java Code:

// Define a public class named Exercise3.
public class Exercise3 {
    // 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 before the character at index 1 in the string.
        int val1 = str.codePointBefore(1);
    
        // Retrieve the Unicode code point before the character at index 9 in the string.
        int val2 = str.codePointBefore(9);
        
        // Print the Unicode code point representing the character before index 1 in the string.
        System.out.println("Character(unicode point) = " + val1);
        // Print the Unicode code point representing the character before index 9 in the string.
        System.out.println("Character(unicode point) = " + val2);
    }
}

Sample Output:

Original String : w3resource.com                                                                              
Character(unicode point) = 119                                                                                
Character(unicode point) = 99
