(Java) “error: cannot find symbol” when compiling?

Question

This is the first time I'm coding in Linux, I'm used with writing in Windows. So my problem: I have a map called Train , in there I have two classes: Train.java and Lab1.java .

When I try to compile(using javac Train.java in the terminal), I get no errors with one of the class, but with the other one I get this error:

Lab1.java:58: error: cannot find symbol
        Train trainThread2 = new Train(tsi, trackSemas, secondTSpeed, 2, true, tsispeed,8);

This code is from the Lab1.java class. It points at the Train and shows this error above, that it cannot find the symbol Train

I didn't find any information that helped me, so I'll try asking here.

Answer 1

Lab1 depends on the class Train so you need to tell the path of the compiled Train class in its classpath. The easiest solution is to compile both at once:

javac Train.java Lab1.java
