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
