1．linux有些自带程序很多是python写的,自带的python2也最好不要升级,不然会有很多问题 2．如果遇到 pkg: error processing package *python* (--configure):这类的问题,可以使用以下问题解决,具体python版本可根据python错误情况变更 mkdir ~/repair_pythoncd ~/repair_pythonapt-get download python3.6-minimal libpython3.6-minimal…

在没有package语句的java类, 我们可以直接使用: javac Test.java 就可以了, 如果Test.java中包含package语句,如:package abc; 编译后,是要求Test.class文件放在abc目录下的 所以这时候就又两种方法达到目的: 1.笨方法,先直接编译Test.java 1.1. javac Test.java 1.2. 然后手动去创建abc目录 1.3. 再把Test.class文件拷贝到abc目录下 2.使用 javac -d 目标目录 类名 eg…

1.若我们在A.java中用到了类B,当我们仅仅用 javac A.java 编译A时,编译器也会去寻找B,若类B依然是源文件,也会自动编译它.在使用javac和java命令时,有一个参数选项 -verbose ,可以显示虚拟机每一步所做的事情. 2.类A已经编译成功后,A中用到的B.class依然不能移走,若此时执行java A ,会报NoClassDefFoundError. 3.编译时,如果程序里用到其它类,不需要该类的源码也一样能够通过编译.这很好理解,我们在编写自己的类时,用到了系统类…
