divided into four classes depending on whether the method has parameters or not, and whether it has a return value:Ø no parameter no return value methodØ non-parametric return value methodØ no return value method with parametersØ method of return value with parameterTaskSmall partners, in the editor, defines a method called print, implements the output information function, and calls the Print method in the Main method. Please check the program code and running results, first understand the met

key, the value will be saved there. The preceding method provides a method for calculating the Hash code based on the return value of hashCode (): The indexFor () method is called to calculate the index of the object that should be stored in the table array. The source code is as follows: static int hash(int h) { // This function ensures that hashCodes that differ only by // constant multiples at each bit position have a bounded // number of collisions (approximately 8 at

listIterator(); } public abstract ListIterator listIterator(int index);} This class uses a large number of Iterator for sequential traversal of sets. Because it cannot be randomly located, this class focuses on sequential traversal. If you want to implement a list set by yourself, it is best to inherit this abstract class, in this way, you don't have to bother yourself to implement so many methods. Struct List is a reality of sub-structure Li
