Here is my code
package com.a;
public class A{}
I compiled using
javac -d . A.java
I gets compiled in com/a/A.claas
Now I created another class
package com.b;
import com.a.A;
class B extends A{}
compiled it with javac -d . B.java
and throwing error
B.java:2: error: cannot find symbol
import com.a.A;
^
symbol: class A
location: package com.a
B.java:3: error: cannot find symbol
class B extends A{}
^
symbol: class A
2 errors
Can anybody help?
The compiler is checking your code, and since you're only compiling class B and not class A at the same time, the compiler throws an error because it doesn't know what A is. So either compile all your classes at the same time with
javac -d . A.java B.java
Or tell javac where to find class of A with the -classpath option. The classpath you specify should either be a .jar file that contains A, or the base directory of your class structure. I.e. if your class A is at /foo/bar/com/a/A.class, your classpath would be /foo/bar/
javac -classpath . -d . B.java
Check out the man page for javac as well.
