1. Is bytecode the format for .java source code file, or for .class file? Hint: Java is cross-platform, or architecture-neutral, because bytecode is designed to be machine-independent, so that with the help of JVM, bytecode can run on different OS and CPU.

2.In a java source code file Welcome.java, we have the following code:

public class TryItOut{ public void Main(){

System.out.println("Try it out);

}

}

So what is wrong with the above code? Please modify it to make it compilable and runnable, and assume you cannot change the file name Welcome.java. Hint: the file name has to be the same as the public class name in a java source code.
