Can you tell how did you run your program?

[kirankumaragnihotram]

am writing program at edit plus
and run by dos prompt
can u pls give answer

[wsaryada]

When you get an error telling that main() method is not found in class that means you are trying to run a class that doesn't have a main() method. That's why I was asking how you run your program. I've executed your program using the following command and it executed.

java MethodOverloading

[kirankumaragnihotram]

shall u send that command please

[kirankumaragnihotram]

fulfill the program and send it once again

How are you executing the code?
What command are you using?
What is the full error that you get (copy and paste it here)?

And please use [code] tags [/code] when posting code.

: main method not found error in class overload2. please define main method as : public static void main (String args[])----------- this s the error




class Overload2{

void test(int a) {
System.out.println("a: " + a);

}

void test(int a, int b) {
System.out.println("a and b: " + a + "," + b);
}

double test(double a) {
System.out.println("double a: " + a);
return a*a;
}
}

class MethodOverloading {
public static void main(String[] args) {
Overload2 overload = new Overload2();
double result;
overload.test(10);
overload.test(10, 20);
result = overload.test(5.5);
System.out.println("Result : " + result);
}
}





this s program

[wsaryada]

If you run the Overload2 class you'll get the error you've described. Because it doesn't have the main() method. You can only run a class that have an entry point, which is the main() method. In your example that would be the MethodOverloading class.

[Tolls]

And you didn't use [code] tags [/code] again...
Oh, and that error doesn't match your code.
'overload2' is not the same as 'Overload2'.
I'm assuming you simply mistyped it, but Java is case-sensitive and that typo could imply another problem you have.
Please ensure the information you provide is correct otherwise we will have trouble analysing your problem.

main method not found error in class . wat s the error?

Your error is that if you have main method in class MethodOverloading that class should be public. For example it could look something like this.

File: MethodOverloading.java

class Overload2 {
      // your code here
}


public class MethodOverloading {
      // your code here

      public static void main(String[] args) {
       // your code here
      }
}

}
