How to set a variable in one class and get it in another
0
Once I have set the "set" method in one class to set my accessor, is it possible to return(get) that variable/string in another class without first having to "set" the variable again?
public class A {
Edits edits = new Edits("hello") }
now I want to access this from class B
public class B {
Edits edits = new Edits();
String hello = edits.getHello(); }
Problem is that there is and error initializing "new Edits()" because it first has to be set.

A class or an instance of a class? If it's a class, and you're talking about a static member, then yes, as long as the application is alive (which depends on the environment we're talking about). If it's an instance, yes as long as that instance is alive.

I didn't make myself clear. Suppose you have a class namedAwith a static setter namedsetA(int a)and a static gettergetA(). You can doA.setA(12)and then from inside another class you can doA.getA(). Is this what you're asking?

are you planning on only creating one instance of a class, like a singleton?

The answer here is actually quite simple. All you do it declare a static variable and call it with the class from another class.
public class Edits {
public static String edits;
}
Set it in another class
public class A {
Edits.edits = "new value";
}
Then get it from another class
public class B {
doSomething(Edits.edits);
}
