Convert to Instance Method

Last modified: 01 August 2022

Convert to Instance Method refactoring lets you convert a static method to a non-static, class instance method, with a class being the type parameter of the initial method.

tip

This refactoring is also available from UML Class diagram.

Example

Consider classes MyClass, ClassB and ClassB residing in the same package.

As a result, MyClass and ClassB become converted.

Before

After

public class MyClass {
     ClassA classA = new ClassA();
     ClassB classB = new ClassB();

     static public void greatMethod(ClassA classA, ClassB classB){
         System.out.println("classA = " + classA);
         System.out.println("classB = " + classB);
     }
     public void myMethod(){
         MyClass.greatMethod(classA, classB);
     }
}
public class MyClass {
    ClassA classA = new ClassA();
    ClassB classB = new ClassB();

    public void myMethod(){
        classB.greatMethod(classA);
    }
}

public class ClassB {
    public void greatMethod(ClassA classA) {
        System.out.println("classA = " + classA);
        System.out.println("classB = " + this);
    }
}
