If the exception data appears in the program, but it does not affect the following program execution, then we should be in the catch block will be differentData is discarded, and then logs are logged. If, it affects the following program to run, then it is better to quit the program.3. The principle of exception handling mechanism in JavaJava handles exceptions in an object

This article describes the Java read WAV file (waveform file) and the method of drawing waveform diagram. Share to everyone for your reference. Specifically as follows: Because a lot of netizens recently asked me about the waveform file reading and writing problems, in order to make everyone more convenient and let the code can get better improvements, I will this part (waveform file read and write) code o

0.So the lock was completely released. The exclusiveownerthread is set to null.Then the waitstatus was changed back to 0. Thread 2 corresponding node will leave the ' waiting queue ' immediately.Thread 3 is awakened.Let state=1, and put the exclusiveownerthread of the lock point to yourself. Represents the thread 3 itself exclusive of this lock.Modify the head pointer, and disconnect the corresponding precursor and subsequent links, so that thread 2 corresponding node leaves the ' waiting queue

Java Draw mathematical function diagram is not very convenient, need to use a third party package jfree, installation or download methods online. To use the xyseries inside the Jfree, generate a series of data. Then, based on the generated data, use chart strokes to paint. Example: 1. Paint y= x^2 import javax.swing.JFrame; Import Org.jfree.chart.ChartFactory; Import Org.jfree.chart.ChartFrame; Import Org.j

ZigZag Conversionfirst, the topic is as follows:The string "PAYPALISHIRING" is written in a zigzag the pattern on a given number of rows type this: (The want to display the this pattern in a fixed Font for better legibility) P A H NA p L S i i GY i And then read on line : "PAHNAPLSIIGYIR" Write the code that would take a string and make this conversion given a number of rows:String convert (string text, int nRows); convert("PAYPALISHIRING", 3) should return "PAHNAPLSIIGYIR" .

same place as the runner1 element, and remember it as walker1. The reason for Walker1 in the front part is that it is impossible to find a larger interval containing the [walker1,runner1] interval so that there is no repetition, because there are already repeating elements in the [Walker1,runner1] interval. So the next target range can only go forward, the lower interval is lost, at this point to the third step;three , the Walker1 front (including itself) lost, the problem back to the first s

' Conditional queue ':Then change the waitstate from-2 to 0:The next thing to do is to detach node from the ' Conditional queue ' (which is the node of thread 1), and end up in the ' Waiting queue '.But the ' Wait queue ' is not initialized at this time, so the ' wait queue ' is initialized before being inserted into ' wait queue '. See:' Wait queue ' is initialized. Next is the thread 1 corresponding to the node, the tail into the ' Waiting queue ':Then the waitstate of the predecessor of the

When you want to do a library project, the picture size, pixel control is the first problem to be solved.One, the single graph produces slightly shrinks the graphDantu is redrawn to generate a new picture. The new diagram can be reduced by a certain percentage from the old picture, or it can be defined as a fixed size.The detailed code is as follows: Copy Code code as follows: Import Com.sun.image.codec.jpeg.JPEGCodec; Import Com.sun.image

software tools available to help software engineers to do the work, either forward engineering or reverse engineering . Forward Engineering is a traditional process of high-level abstraction, logic and independence design for a system physical structure implementation. Reverse engineering is the analysis and processing of an existing system to identify its components and their intrinsic relations, so as to build a framework of a system with high-level abstraction. In mos

Before learning the object-oriented design patterns, Java interfaces and abstract classes are vague and hard to understand. When I first learned the Java language, it was hard to understand why the concept of interfaces was required. Although multi-inheritance can be implemented, there is only a method name and no method body, how can I implement it? I can't get anything from it. Except for some method name

Inheritance relationship inheritance refers to the ability of a class (called a subclass, sub-interface) to inherit the functionality of another class (called the parent class, parent interface) and to increase its own new functionality. Inheritance relationships in Java are clearly identified by keyword extends and ar
