没学过 这是什么错.Line 0, column 0: could not parse error message: import java.util.ArrayList?



------解决方案--------------------
The major.minor version '49.0' is too recent for this tool to understand.
说明用于编译和运行java class的JDK版本不同. 

在命令行下打
java -version
可以看到运行时所用的JDK的版本. 

确认你的编译环境用了同样的JDK版本.
------解决方案--------------------
用二进制编辑器，如ultraedit打开java class文件，头八个字节的后面两个是这个class文件的主次版本号，如jdk1.5编译器编译出来的class文件的头八个字节是 

CA FE BA BE 00 00 00 31 版本号是49.0 
头四个字节是java字节码的魔数 magic number,是一种咖啡的名字 cafe babe,它表明那是个java的字节码。 

如果用jdk1.5的编译器 javac，用参数 -target 1.4 可以制定编译出的目标代码能在jvm1.4下运行，也就是版本为48.0的class
