This chapter describes the Java Virtual Machine class file format. Each class file contains the definition of a single class or interface. Although a class or interface need not have an external representation
注:在Java字节码中,所有boolean、byte、char、short类型都是用int类型存放,因而在常量池中没有和它们对应的项。 2.3.1CONSTANT_Class_info 用于记录类或接口名(used to represent a class or an interface) CONSTANT_Class_info format 注:在Java字节码中,类和接口名不同于源码中的名字,详见附件A. 2.3.2CONSTA...
控制台的报错: java.lang.ClassFormatError: Incompatible magic value 0 in class file网上搜了一下它的意思是java.lang.ClassFormat错误:类文件中的幻数值0不兼容,位置也刚好就是:jsp/back/backIndex.jsp(我的后台首页), 明明我啥也没改,而且昨晚睡觉前运行项目的时候还是好好的,我clean了好几遍也没用,然后我...

In Java, every compiled Java source file is converted into a binary format called a class file. This class file contains the bytecode representation of the Java code, which is then interpreted and executed by the Java Virtual Machine (JVM). Each version of the Java compiler produces a specif...
