Question

Constructor:

-empty body

Class method 1: goodFriend

- return string value, "I like you!"

Class method 2: badFriend

- return string value, "I don't like you!"

Main Method:

- create new Friend object

- call goodFriend and badFriend using Friend object

/* class header */ {

/* constructor method header */ { }

public static void main (String [] args) { Friend f = /* new Friend object */

// call goodFriend using Friend object

// call badFriend using Friend object

}

public /* return type */ goodFriend() {

return "I like you!";

}

public /* return type */ badFriend() {

return "I don't like you!";

}

}

Answer 1

So In this program I will show you how to call the method using object as per given requirements

In this Program I use two diffrent Method which Returning some string value

1>public String goodFriend()

which is returning "I like you!" String

2>public String badFriend()

which is returning "I don't like you!" String

Code:

public class Friend {
    
    public Friend()
    {
        //Default constructor invoked when the object is created....
    }
    public String goodFriend()
    {
        return "I like you!";
    }
    public String badFriend()
    {
        return "I don't like you!";
    }
    
    public static void main(String[] argv)
    {
        Friend f=new Friend();//this statement invoke constructor which is basically used to assign the memory to the recently created object
        
        
        //f.goodFriend() this statment is returning a string value that's why I directly write it into the Print Statement 
        System.out.println(f.goodFriend());
        
        
        // You can also use the following approach where you have to first store the returning value into the variable and then print it
        String data=f.badFriend();
        System.out.println(data);
    }
    
    
}

Output

I hope you will undestand how to call the function and using Object
