sufficient to save all the elements, without wasting too much space:If there is no extra space, we will double the length of the array;If the stack size is less than One-fourth of the array, we will halve the length of the array.In this implementation, the stack never overflows, and the usage is never less than One-fourth (unless the stack is empty, in which case the array size is 1).The textbook has the source code, fully understand!5. Even if the use case no longer requires this element, the
does not initiate assertions, and you can use the-enableassertions flag (abbreviated as-EA) at the command line to start the assertion. The purpose of the assertion is to debug: The program should not rely on assertions in normal operations, as they may be disabled. The system programming course learns to use assertions to ensure that the code is never terminated by a system error or into a dead loop. (? )10. If you always complain about the nature of programming language, then you can only des
exception.4. Familiarize yourself with the typical array processing code (P11-P12):· Find the largest element in an array· Computes the average of an array element· Copying an array· Reverse the order of array elements· Matrix multiplication (Phalanx)-a[][] * b[][] = c[][]5. The array name represents the entire array-if we assign an array variable to another variable, then two variables will point to the same array. If you want to copy an array, you should declare, create, and initialize a new
than This.4. A backpack is a collection data type that does not support removing elements from it-its purpose is to help the use case to collect elements and iterate through all the collected elements (use cases can also check whether the backpack is empty or get the number of elements in the backpack).Using bag can indicate that the order in which elements are processed is Unimportant.5. A classic reason to use a stack iterator in an application is to reverse their relative order while preserv
Summary: As the name implies.Focus:1. Geometric objects: A Natural example of object-oriented programming is designing data types for geometric objects.Point2d.java is a data type for points in the plane.Interval1d.java is a data type for one-dimensional intervals.Interval2d.java is a data type for two-dimensional intervals.Interested to study!2. The Java language provides special support for string initialization and connection: We can create and ini

Java is based on C + +, but Java is a more purely object-oriented programming language, unlike C + +, Java only supports object-oriented programming, so Java programming style is also pure OOP style, that is, everything is a class, everything is done in the class object.In Java
difference between the inheritance and interface, the book is very vivid examples, fish can swim, sharks are fish, clown fish is fish, so they are inheritance relationship, but people can swim, but people and fish there is no inheritance relationship, but the human and fish between the connection can be expressed by the interface. While this is understood, I cannot relate to how much of a difference these two definitions can have in a particular program. In short, to continue to learn or to fil
