Created a new class as per given prototype, but it shows error

Question

public class test {
void Test() {
System.out.println("First ever class in Core Java");
}
}
class trya {
public static void main(String[ ] args) {
test a = new test();
a.Test();
}
}
.....................................
This code gives the follwing error:
Error: Main method not found in class test, please define the main method as:
public static void main(String[] args)
or a JavaFX application class must extend javafx.application.Application
............................................................
Even though the defined prototype is :
public class Animal {
void bark() {
System.out.println("Woof-Woof");
}
}

class MyClass {
public static void main(String[ ] args) {
Animal dog = new Animal();
dog.bark();
}
}
which is giving output.

Answer 1

Like java complain, you have to add main method to "test" class

Answer 2

why do I need to add main method in test class??

Answer 3

When you run a program in Java it will look for the main method in the public class from that file. And also you can only have 1 public class per file. Therefore you have to either change the visibility of the classes or move the method main to the public one!

Oh and just a reminder: Classes always start with upper case letter and methods with lower case ones!

Answer 4

How come does the compilation of the protype does not give the error??

Answer 5

Shivdutt Dixit depends in how you're executing, are those 2 classes in the same file?

Answer 6

yes they are in the same file
