The value after the = is the String returned by the Object class's default toString method. The Time1 method needs a toString method that returns the String you want to see.
What happened to the toString method that was in earlier versions of the Time1 class? Copy it into the new version. See post#31

it was with string.formatter and i am not allowed to use it

What else is not allowed?

Can you build a String using concatenation(using + operator) and return that in the toString method?

public String toString() {
        final StringBuilder sb = new StringBuilder ("Time1{");
        sb.append ("_hour=").append (_hour);
        sb.append (", _minute=").append (_minute);
        sb.append ('}');
        return sb.toString ();
    }

but now how can i dispose the part that i dont need so the out put will be

1. Testing Constructors and toString:
	t1=17:45
	t2=00:00

Why not build the exact String you want so nothing has to be removed or changed?

Again I can not see what you are seeing so I need you to paste it here so I can see what you are talking about.

i managed to figure it out now to my next question how the method minFromMidnight will look like
this method returns how much minutes passed after midnightfor example if the time stored inside the object is 07:30 than a value of 450 will be returned

i got no idea how to do that

Expressions in java use standard math symbols: +, -,*, / for add, subtract, multiply, divide
Take a look at the tutorial: https://docs.oracle.com/javase/tutor...bolts/op1.html

How did you get the value of 450?

60*7+30

Now replace the 7 and 30 with the variable names from the class and assign the results to a variable.

 public int minFromMidnight()
    {
        return _hour+_minute*60;
    }

??? like this
