Ugly number IIWrite a program to find the n -th ugly number.Ugly numbers is positive numbers whose prime factors only include 2, 3, 5 . For example, is the sequence of the first 1, 2, 3, 4, 5, 6, 8, 9, 10, 12 10 ugly numbers.Note that's 1 typically treated as an ugly number.The time complexity will be high if the number is not ugly by the judge. Here can be used to determine how many primes in K this problem solution, a little flexible.The first 1 is ugly number, and the following is the minimum

Java Basic type wrapper class:Basic data type Basic type wrapper classBYTE byteShort Shortint IntegerLong Longfloat floatDouble DoubleChar CharacterBoolean BooleanHere is a representative explanation of the integers and charater classes.Integer classThe Integer class wraps the value of a primitive type int in the object. The class provides several methods for converting between int and String types, as well as some constants and methods that are useful when working with int types.Member variable

of wrapper class is the class, which is the reference variable in the program. therefore, they are stored in memory in different locations: The base type is stored in the stack, and the base type wrapper class is stored in the heap. The packaging classes mentioned above all implement the constant pool technique, while the other two types of floating-point-type wrappers are not implemented (double, float). In addition, the string type implements the constant pool technique. Instance:1 Public cl
