Java String Exercises: 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:

public class Exercise3 {

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

Sample Output:

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