     // Create two char objects.
	char high = '\ud800';
	char low = '\udd10'; 
     // Converts the specified surrogate pair into its respective supplementary codePoint
        int result = Character.toCodePoint(high, low);	
     // Print the result
	String str= "The result for the above charactetr is given as:"+result;
        System.out.println(str);

     // Converts the specified surrogate pair into its respective supplementary codePoint
        int result1 = Character.toCodePoint(high1, low1);
        int result2 = Character.toCodePoint(high2, low2);        
     // Print the result.
	String str1 = "The result for the above character is given as:"+result1;
        String str2 = "The result for the above character is given as:"+result2;
