This is the code i have written

//Demonstrate Method Overloading.
class OverloadDemo
{
void test()
{
System.out.println("No parameters");
}

//Overload test for one integer parameter.
void test(int a)
{
System.out.println("a: " + a);
}

//Overload test for two integer parameters.
void test(int a,int b)
{
System.out.println("a and b: " + a + " " + b);
}

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


class Overload
{
public static void main(String args[])
{
OverloadDemo ob = new OverloadDemo();
double result;

//call all versions of test()
ob.test();
ob.test(10);
ob.test(10,20);

result = ob.test(123.2);
System.out.println(result);


}

}

Now when i am compiling this program it's showing no errors,but while running the notepad containing the code is getting displayed

[goldest]

Well, your code ran fine with me.

What are the command line arguments you are using to compile and run this?

Goldest

[Gousia]

To compile i am using

javac <programname>.java

and to run

<programname.java

[goldest]

You should use,

To Compile: javac Overload.java

To Run: java Overload

[Gousia]

But the name of my class is OverloadDemo so i have saved it wiith the same name

Now if i tried to execute it as you specified it's throwing an error of file not found

[Gousia]

I think i have to save it with the class name that contains main method-- Is it

[Gousia]

But still its showing the same notepad

[goldest]

Yeah. You are supposed to run the java file that contains the main method. In your case it is, Overload.java

If you try to use java command on file with no main method, there will be error saying, "NoSuchMethodError: main"

I hope you are clear with that,

[Gousia]

Got it

I was doing a mistake
For running i was using Overload java
now by java Overload it worked fine


Thanks a lot for your help,,thanks
