Last week, I learned about the swing user interface components and designed the different interfaces by adding the elements in the swing package to the framework. You can use trim to go out of the space entered in the text input field, the SetText method changes the contents of the Text field, and the GetText method to get the user to type the text. In this chapter, the event response processing methods mostly use lambda expressions. You can create the interface you want by adding the required c

directly turn it into an executable jar file in the Control panel I still stuck in the last side, not open, jar file, tried several times to no avail. then is Applet,applet can embed the Web page, in other words, the applet is included in the HTML page of the Java program, in the freshman time we learned HTML, so the name of this HTML is not unfamiliar to us, it is difficult to embed the applet in it , although this part is selective learning but I still want to try it later, one is very curiou

Finished the four, five, six chapters of the content, we this week's Java learning into the anomaly, assertions and logs, remember that the teacher said that three chapters is the core of Java, is the core will be more difficult, anyway, I learned when the confused. After I learned the anomaly, the assertion and the log, I regained confidence in Java.This week's learning content is not very difficult, coupled with the teacher explained in detail again, I have the exception and assertion of the g

There are two ways: 1. Catch the exception and handle it yourself. 2.throw go out and let someone else handle it.As an example:public class a{ try{ A statement that could release an exception ... }catch (Exception e) { E.getmessage ();//Handle yourself }}public class A throws exception{ A statement that could release an exception ...}//throw out and let someone else handle it.Note that this is throws.If you use the throw in the methodExample:public class a{ try{ A state

Java Nineth Week learning experienceThrough this week's study, learned the exception assertion and the log, has learnt to enable the assertion in the Eclipse compiler, but, regarding the exception, in the shorter teacher teaches the instance the procedure to be able to catch the exception, but in the Long program task Seven task Eight does not know is what kind of exception, No exception catch exception should be added, task nine does not define the L llegalscoreexceptionIllegalnameexception exc

This week has learned about exceptions and assertions, and it is easier and more manageable to call the system to customize the exception class. But when you define an exception class, you don't know what to do when you use it. In the last experiment, when the first character in the name is a number, there is a problem in catching the exception, writing the code but not the result. Results of less than 0 and greater than 100 can come out, but the format is not very correct. I hope the teacher ca

In the sixth chapter of the study, the concept of deep copy and shallow copy is clearly understood. All constant members and base type properties for a shallow copy of a copied object have the same copy value as the original object, and if the member field is an object, the object reference to the object field of the copied object still points to the original object. Deep copy, all member fields of the copied object contain the same value as the original object, and the Object field will point t

non-static fields of the current object to the new object, whether the field is a value type or a reference type. These two copies are called Light and deep copies, respectively. in my opinion, the dead point of a shallow copy is that the original object and its copy refer to the same object, while a deep copy keeps them from pointing to the same object. Overall, this week's study is very rewarding, but in the experiment still encountered a lot of difficulties, interface settings, sub-class fun

this week, after reviewing the interface, I learned about the use of internal classes. An inner class is a class that is defined inside another class, and the outer class is called an outer class, and after learning the inner class, think about why you should learn the inner class, for three reasons:1), the inner class method can access data in the scope where the class definition resides, including private data.2), inner classes can be hidden and not seen by other classes in the same package.3)

Linux Partitioning knowledgePrimary partition, extended partition, logical partition1, a hard disk can have up to 4 primary partitions (primary), where one primary partition can be replaced by an extended partition (extend), only one extended partition, within the extended partition can be divided into multiple logical partitions (L).2. If you plan for more than four partitions: the partition combination is 3primary+1extend or 2p+1e or 1p+1e.3, a disk can only be an extended partition, the exten

coins respectively, 14 of the position if the allocation of 3 gold coins can not meet more than 13 of the conditions, so 14 of the position allocated 4 gold coins. Therefore, the local maximum value corresponds to a larger number of gold coins when the local maximum value is incremented from both sides to the local max position. For the leftmost and most right position of the sequence, if the first number is less than/greater than the second number, then it is the local minimum/large value,

Startup and creation of threadsThread Class (Java.lang.Thread Class)In the Java language, the thread class represents threads, and all thread objects must be instances of the thread class or its subclasses. The role of each thread is to accomplish a certain task, in fact, to execute a program flow, also known as a sequential execution of code, Java uses the Run method to encapsulate such a program flow.Inherit the thread class to create and start threads1. Define a subclass of the thread class a
