And this time, we know that what is actually needed is a subclass object.If the method is called only once, we can use the format of the anonymous inner class to simplify. (First of all, the formal parameters of the method we've tal

positive and negative signs of the bit, in the lowest bit will be with the actual data error, in simple terms, we give the value, in In most cases it takes more than 64bit of digits to be accurately represented (even in the case of an infinite number of bits), whereas a double type has a value of only 64bit, and the number of digits behind it will definitely bring an error, and the result of "mathematically accurate" cannot be obtained.8,A: When using the BigDecimal (double) constructor, accura

---restore content starts---1. Can there be only one public class in a Java class file?There can be at most one public class in a Java source file, and when there is a public class, the source file name must be the same, otherwise it cannot be compiled, and if there is no public class in the source file, the file name does not have a consistency requirement in the class.The main () does not have to be place
