Depends on which object u invoke on run time..
when these file containing these classes are compiled, (assuming u have a public class in that file), A.class and Test.class would be created..

then if you enter java A, then main inside A would be executed.. if you enter java Test, then main inside Test would be executed..

When any java file has more than one class and those classes if have different main() then the class which will be loaded by jvm, will be run and it's main method will be executes. And let you save your program by "a.java"

for your code


1. Javac a.java // will create a.class file and test.class file
now,

for output on console as hi friend... You need to write java a
i.e you have loaded a class and it's main() will execute, now same for test.class .. You need to write java test and it will result in how are you

It will give error because first u creating a class and after that closed the class and again u create a class with main method.This is invalid. it is possible to create double main method in a program but when the first class will be closed then it will give error at compile time...

  1. span style="color: #0000ff;">"Hi Friends""How r u?"

It depends which class file main method you invoked.
because two separate class file generate as soon as it is compiled by the JVM.
