Java与equals和compareTo之间的区别

public class StringDemo {

   public static void main(String[] args) {

      String str1 = "tutorials", str2 = "point";



      // comparing str1 and str2

      int retval = str1.compareTo(str2);



      // prints the return value of the comparison

      if (retval < 0) {

         System.out.println("str1 is greater than str2");

      } else if (retval == 0) {

         System.out.println("str1 is equal to str2");

      } else {

         System.out.println("str1 is less than str2");

      }

   }

}
