configured as "Java (TM) platform SE binary", you can also double-click the jar file for execution) 4. all strings have the same hashCode and are not necessarily equals. How to construct two strings so that their hashCode is the same and the strings are different? First, to simplify the problem, we can limit that the

=2^3, there are digital 0, 1, 2, 3, 4, 5, 6, 7, and each digital exactly corresponds to three-bit binary number, so octet can well reflect the binary.Hex: Hexadecimal number has two basic characteristics: It consists of 16 characters 0~9 and a,b,c,d,e,f (they represent the decimal number 10~15), the hexadecimal number operation law is every 16 into one, that is, the base r=16=2^4, usually in the expression with the tail mark H or subscript 16 to show

, like rice teacher said, all the programming language is the same, since the study of VB, with the VB map, it seems that all the language has become simple. First of all, to know it, macro overall grasp, and then also to hands-on practice, from the practice of understanding the charm of programming language, to know its why.After reading J2SE's video, the most impressive is the Java API Development documentation, very powerful, the following is my ma

): properties and methods that are modified by private can only be used inside that class4). Default (no access modifier): used within the class and the class under the same package. instanceof: Determines whether an object is an instance of a class. Syntax form: Reference name instanceof class name (interface name), returns a Boolean value. The return value is also true when the class name is the parent class name. Comparison of equality (= =)1). For native data types, the comparison is betwee
