Java Program to Determine the Unicode Code Point at a given index
In this article, we will understand how to determine the unicode code point at a given index. Each character is represented by a unicode code point. A code point is an integer value that uniquely identifies the given character. Unicode characters can be encoded using different encodings, like UTF-8 or UTF-16.
Below is a demonstration of the same −
Suppose our input is −
Input String: Java Program Index value: 5
The desired output would be −
Unicode Point: 80
Algorithm
Step 1 - START Step 2 - Declare a string value namely input_string and two integer values namely index and result Step 3 - Define the values. Step 4 - Use the function codePointAt() to fetch the code point value. Store the value as result. Step 5 - Display the result Step 6 - Stop
Example 1
Here, we bind all the operations together under the ‘main’ function.
import java.io.*;
public class UniCode {
public static void main(String[] args){
System.out.println("Required packages have been imported");
String input_string = "Java Program";
System.out.println("\nThe string is defined as: " +input_string);
int result = input_string.codePointAt(5);
System.out.println("The unicode point at index 5 is : " + result);
}
}Output
Required packages have been imported The string is defined as: Java Program The unicode point at index 5 is : 80
Example 2
Here, we encapsulate the operations into functions exhibiting object-oriented programming.
import java.io.*;
public class UniCode {
static void unicode_value(String input_string, int index){
int result = input_string.codePointAt(index);
System.out.println("The unicode point at index " +index +"is : " + result);
}
public static void main(String[] args) {
System.out.println("Required packages have been imported");
String input_string = "Java Program";
System.out.println("\nThe string is defined as: " +input_string);
int index = 5;
unicode_value(input_string, index);
}
}Output
Required packages have been imported The string is defined as: Java Program The unicode point at index 5is : 80
