Line: 2, Column: 3 Method does not exist or incorrect signature: void show() from the type Child2.

Above is the error im getting. How can I rectify it?

public Virtual class Parent2 {
public string name;
    public string branch;
    public virtual void show(){
        name='kiran';
        branch='vijayawada';
    }
    public void invoke(){
        system.debug('Name:'+name);
        system.debug('Branch:'+branch);
    }

}
public class Child2 Extends parent2 {
    public integer age;
    public String phone;
    public override Void Show(){
        name='ravi';
        age=90;
        branch='mpl';
        phone='1111';
    }
    public void Display(){
       system.debug('Name:'+name);
       system.debug('Age:'+age);
       system.debug('Branch:'+branch);
       system.debug('Phone:'+phone);
    }
}

Execute:

Child2 c=new Child2();
C.show();
C.display();

  • Can you provide more details as where/when are you receiving this error? Is it compile time, runtime, in a test class?

  • It's working at my end...just executed my developer console....only difference I can see your method name is started with cap S...and your calling with lower s...but case-sensitivity should not be problem in apex.... Are your running your code in Dev Console?

I believe the issue is due to our use of the Virtual keyword in the Parent2 definition. According to the documentation, classes defined in Execute Anonymous are considered virtual by default.

Be removing the virtual keyword from the class definition, I was able to get this to compile and run as expected in my environment.

public class Parent2 {
public string name;
    public string branch;
    public virtual void show(){
        name='kiran';
        branch='vijayawada';
    }
    public void invoke(){
        system.debug('Name:'+name);
        system.debug('Branch:'+branch);
    }

}
public class Child2 Extends parent2 {
    public integer age;
    public String phone;
    public override Void Show(){
        name='ravi';
        age=90;
        branch='mpl';
        phone='1111';
    }
    public void Display(){
       system.debug('Name:'+name);
       system.debug('Age:'+age);
       system.debug('Branch:'+branch);
       system.debug('Phone:'+phone);
    }
}

Child2 c=new Child2();
C.show();
C.display();
