修改JAVAINSTALLPATH 为JAVA SDK 安装目录（默认用C:\PROGRAM FILES\JAVA\）即可；

只在 用户变量下 创建，会事先保存好用户原有的“JAVA_HOME,JRE_HOME,PATH,CLASSPATH”等变量到"OlD-JAVA_HOME,JRE_HOME,PATH,CLASSPATH.TXT"（按JAVA_HOME,JRE_HOME,PATH,CLASSPATH顺序保存），然后删除用户JAVA_HOME,JRE_HOME,PATH,CLASSPATH”变量，并创建JAVA SDK变量。之后会打开环境变量设置窗口和"OlD-JAVA_HOME,JRE_HOME,PATH,CLASSPATH.TXT"，按需补充原有变量值。
