java packages: cannot find symbol

Question

I\'m having a strange error. I have 2 classes in the same package but they can\'t find each other. From what I remember, as long as the classes are in the same package, they

Answer 1

Since you're compiling Java files that are in distinct packages, you'll have to ensure that they compile to the appropriate directories.

You can use this invocation to do just that. Substitute $SRC with the location of your source files, and you can let $BIN be the current directory, or some other location on your machine.

javac -sourcepath $SRC -d $BIN A.java B.java

When you want to run them, you have to add them manually to the classpath again (but that's not such a bad thing).

java -cp $BIN com.mypackage.B

This invocation should work; just made sure of it with A.java and B.java residing on my desktop. With the -d flag, that ensured that when they compiled, they went to the appropriate package folder scheme.

Answer 2

It should be:

A.java

package com.mypackage;
class A {
    public static int read(){
       //some code
    }
}

B.java

package com.mypackage;
class B {
    public static void main(String args[]){
       int x = A.read();
    }
}
