Overriding

[archu sweet]

public class A {
	public void doit() {
		System.out.println("hi");
		 }
	public void doit() {
		System.out.println("hsdsi");
	     }
		 public double doit(int x) {
		 return 1.0;
		 }
		 public static void main(String args[])
		 {
			 System.out.println("hi");
		 }
}

I just wanted to know what is wrong in the above code ?

It is throwing this error : Exception in thread "main" java.lang.Error: Unresolved compilation problem

[Jesper de Jong]

An error like "unresolved compilation problem" probably means that you have some old *.class files somewhere and that the compiler gets confused. Delete all your *.class files and re-compile everything again.

What is wrong: Look at lines 2 and 5. What do you think could be wrong there?

i think overriding of same functions is not possible in same class....am i correct??

[Rob Spoor]

Yes. Overriding can only be done by subclasses.

You are doing overloading not overriding.

He is doing neither.

You have two doit() methods - the same name, the same arguments. When you call doit() (without arguments) on an A object, how is Java supposed to know which of the two to call?

oh,my god.you define tow same methos in the same class.
if you want override a method.you first have to inherit another class.
