运行Java文件时出错

Question

I have two files like read.java and sufer_type.java . The surfer_type.java needs some methods which are present in a .jar file. Before executing surfer_type.java I need to run read.java and use the data from read.java . So I used the statement:

read r=new read();

in surfer_type.java and I am compiling surfer_type.java like:

javac -classpath netcdfAll.jar surfer_type.java:

But I am getting an error:

surfer_netcdf.java:30: cannot find symbol
symbol  : class read
location: class surfer_netcdf
 read r = new read();
  ^
surfer_netcdf.java:30: cannot find symbol
symbol  : class read 
location: class surfer_netcdf
 read r = new read();

Answer 1

You are trying to instantiate a class read , which it is telling you does not exist (or rather, it cannot find).

Make sure the class exists and is properly imported in the class where you are trying to use it.
