无法从类型teaminfo对非静态方法acceptadd（String）进行静态引用

Question

Currently, I am trying to make a couple of methods access each other. However, I am getting an error that I have not been able to figure out.

This is the error I get:

Cannot make a static reference to the non-static method acceptadd(String) from the type teaminfo

I looked to see if a method or a variable was static when it was not supposed to be, but neither the method acceptadd(String) or the method I am calling it from is static. I have no idea on how to fix it on this point, can someone help me?

Here's my code for GuiAddReject:

The error Cannot make a static reference to the non-static method acceptadd(String) from the type teaminfo is at this line:

        teaminfo.acceptadd(playername);

Here is teaminfo.java:

Any help would be appreciated.

Also, sorry about the links, couldn't get the code brackets to work...

Answer 1

The problem is that you're trying to call an instance method as if it were static.

On the line that you cited:

teaminfo.acceptadd(playername);

teaminfo is a class name, not a variable referring to an instance of that class. You want to create a teaminfo object somewhere in your project, eg in GuiAddReject, and call the methods on that object.

Answer 2

The error means that you are trying to access a non-static method ( acceptadd ) from a static context (ie not from an object). To solve this you need to make an object of the class to which the method you want to call belongs and call the method from its reference.

for example the correct way would be:

teaminfo tf = new teaminfo();
tf.acceptadd(playername);
