The solution has the following two kinds:Scenario 1. At the project name, right-click the property, open the Project Properties dialog box, locate Myeclipse-->project Facets, and set the Java version here to be the same as the project compile level.Scenario 2. Locate the file named Org.eclipse.wst.common.project.facet.core.xml in the "Project/.settings/" directory, Java
Learn Java for some days, always use the IDE to write programs. The advantage is that I can even compile with the command line, explaining that the Java source code is not known, it is not clear how the compiler and virtual machine (including bytecode interpreter) in the JDK are positioned to the class file.

When writing code, we often mention two principles:
1. the method should be as short as possible, and the large method should be divided into small ones;
2. Do not reinvent the wheel.
When we emphasize these two principles, we often focus only on the Code concise, easy to maintain, and other factors that facilitate us. In fact, this can also greatly facilitate the Java

Basic knowledge:What is the anti-compilerAs we all know, the process of converting source code to binary execution code is called "compiling", such as compiling C source code into EXE executable file, then the process of binary code execution is called "anti-compilation", such as converting EXE to C source code is called "Anti-compilation".Since the mainstream C compiler has been optimized for code, it is very difficult to decompile the exe file gener
A Java Virtual machine (JVM) is an imaginary computer that can run Java code. As long as the interpreter is ported to a specific computer based on the JVM specification description, any compiled Java code can be guaranteed to run on that system. This article begins with a brief introduction to the process of compiling from the

I recently read computer system elements and read some basic things. I found that it would be nice to read this book before the university course compilation. Although some of it is difficult, it is still possible to browse it. After reading this article, you will know how to use this compilation item. The same is true for model-based elec
Today we are going to share some of the reverse compiler tools on Java, which sounds like a very high technical vocabulary, in layman's terms, it is a process of reverse analysis of the target executable program to get the original code. In particular, a programming language running on a virtual machine such as. NET and Java is easier to decompile to get the sour
