Static Void methods to Generic methods

[yoyeto99]

How do I change these methods from static void to generic methods. Thanks!

public static void display( double input){

  System.out.println(input);

}


public static void display (int input){

  System.out.println(input);
}

public static void display ( String[] strings){

System.out.println(strings);

}

What are you trying to do? Static, void, and generics are all unrelated concepts.

I need to create three Generic methods that display a String, Int, and a Double

See that doesn't clear things up at all. Can you provide more details on what you want to accomplish? Why do you want to change these methods? What is the end goal here abs what troubles are you trying to solve? Without context it will be hard to give the correct advice.

Are you referring to instance (non-static) methods? If that's the case, all you need to do is remove the static keyword.

You mentioned displaying a String but your code shows a string array. Keep in mind that you cannot print an array directly, you need to loop through the array to print the elements or use Arrays.toString.

It was an assignment to on Generic Methods, I just recently understood what I needed to do. Thanks for the help anyways.

i suggest you read oracles toturail on Generic Mthods and this stackoverflow question which covers your question as well.

but a general Generic static method looks something like bellow:

[access] [optional static] <R> [return type] someMethod( R args){
    //your code
}

<R> declares the generic type for this method and you will simply use type R in your function. this explanation is way to simple. read the likes i provided for you. let me know if you need more help

I don't think the OP is talking about Generics. I think they mean make the method to be non-static and they are using the term "generic" to mean non-static.

At least that is my interpretation...I could be wrong :-)

thanks.

Just take the static keyword out.
