Below is the Java program demonstrating how to find the Unicode value of a Character in Java:

 public class UnicodeCharacterValue {
  public static void main(String args[]) {
    String str = "Alive is Awesome";
    char givenChar = str.charAt(2);
    String unicode = getUnicodeValueOfChar(givenChar);
    System.out.println("Unicode value of i is: " + unicode);
  }
  
  public static String getUnicodeValueOfChar(char ch)
  {
      return String.format("\\u%04x", (int) ch);
  }
}

Output:
Unicode value of i is: \u0069
