Thread: Time Class problem

hi guys please help i got a problem with time programming
in my code there is a main class named Time1
than it supposed to contain 2 instance variables int _hour - representing the time (0-23)
and int _minute - representing the minute(0-59)
than in this class there is a constructors one named public Time1(int h,int m)
how do i begin Please Help me

i looked every where the problem is not with creating class but working with time package et'c

take a look at the final output i added maybe this will tell you what is my strugle

Please edit your post and wrap your code with code tags:

[code]
**YOUR CODE GOES HERE**
[/code]

to get highlighting and preserve formatting.

how can i clone the first output to the second out put t1 and t2 should output same

If t1 and t2 are instances of the same class, then the String returned by the toString() method should be formatted the same way.

public Time1(Time1 t2)
    {
        return ;
    }

is this ok ?

It appears not to do anything.

so how can i duplicate the output ??? can you show me please

   // print two duplicate lines
   System.out.println("a line");
   System.out.println("a line");

Otherwise please explain and show an example of how you print the one line you want to duplicate.

Time1 t2 = new Time1(t1);
        System.out.println("\tt2=" + t2);

first line appears to be an object which requires construct in the main class file

Time1 t2 = new Time1(t1);
creates an instance of the class Time1 by calling its constructor?

What is the main class file? Is that the file that holds the declaration for the class with the main() method?


Does that refer to a line of code?

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

just help output this lines please and that will do enough

Post the code and the output it creates when executed.

When that works, we'll work on outputting the second line.

public Time1(int h, int m)
    {
        this._hour   = (((h >= 0) && (h < 23)) ? h : 0);
        this._minute = (((m >= 0) && (m < 59)) ? m : 0);
    }
    public String toString()
    {
        return String.format("%02d:%02d",_hour,_minute);
    }

Post that code and also copy and paste here the output that it creates when it is executed.

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

this is first input i am missing the t2 = 17:45

System.out.println("\n********** Test Time1 - Started **********\n");
        System.out.println("\n1. Testing Constructors and toString:");
        Time1 t1 = new Time1(17, 45);
        System.out.println("\tt1=" + t1);
        Time1 t2 = new Time1(t1);
        System.out.println("\tt2=" + t2);

this is the class testing

Can you put that code in a method that is in a class with a main method so that the code can be compiled and executed?

i am required to build a class named Time1 and than run the test class on the Time 1 class to see its compiling without errors

public class Time1StudentTester
{
    public static void main(String [] args) {
 
        System.out.println("\n********** Test Time1 - Started **********\n");
        System.out.println("\n1. Testing Constructors and toString:");
        Time1 t1 = new Time1(17, 45);
        System.out.println("\tt1=" + t1);
        Time1 t2 = new Time1(t1);
        System.out.println("\tt2=" + t2);

i only need to build for now this part of the final output
