Access Modifiers

[trupti zanjad]

class Zoo
{
public String coolMethod(){
return "Wow baby";
}
}

class Moo
{
public void useAZoo(){
Zoo z=new Zoo();
//If the preceding line complies Moo has access the Zoo class.
//But... does it have access to coolMethod()?
System.out.println("A Zoo says " +z.coolMethod());
//the preceding line works because Moo can access the public method
}
}
i have complied this code and when running the program it exception java.lang.NoSuchMethodError:main
this examples is from K&B page no 25
there is point, "whether method code in one class can access a member of another class"
please guide me for the above code.

thank you,
trupti.

Howdy!

java.lang.NoSuchMethodError:main

Your problem has nothing to do with access.
When you want to run a program by typing java Moo then Moo has to have a main method.

can you please tell me what is the file name
it its Moo.java then it must be public
only one public class can be exist in a single file

[Burkhard Hassel]

If there is one public class in a file then the file name must be the name of the class.
If there is no public class in a file then the file name can be any.
There cannot be more than one public class in one file.
