public static void main(String[] args) {  
char firstValue = 'A';  
char secondValue = 'B';  
// compare the first char to the second  
    int compareOneTwo = Character.compare(firstValue, secondValue);  
    if (compareOneTwo> 0) {  
    System.out.println("First value is greater than second value");  
    }  
    else {  
System.err.println("First value is less than second value.");  
    }  
   }  
}

// OUT:  First value is less than the second value.

		char secondValue = 'B';
		// compare the first char to the second
    	int result = Character.compare(firstValue, secondValue);
    	if (result == 0) {
      		System.out.println("The chars are the same.");
    	} else {
          	System.out.println("The chars are different.");
