Help with convertMills

[jca613]

i have hard time doing this program.a example i have to is a string returning as hours:minutes:s econds, like convertMillis(5 500) returns a string 0:0:5, convertMillis(1 00000) returns a string, 0:140:. and convertMillis(5 55550000) 154:19:10. i am like having a brain bust lately and cant figure how to come make one and compile.Anyone help me? i have to make millseconds to hours:minutes:s econds

Converting Milliseconds to Time

import java.util.*;
public class hw_6 {
public static void main(String[] args){
}

public static void convertMillis(l ong millis){
System.out.prin t("How much Millseconds ");
long Millis =0;
long time = Millis / 1000;
int seconds = ((int)(time % 60));
int minutes = ((int)((time % 3600) / 60));
int hours = ((int)(time / 3600));

}
}

okay i got part of it right i think. i am trying prompt user to end amount of milliseconds so that it will convert into time.

in this fromat(hh:mm:ss . please help me as quickly as possible please. the more i understand then better.

Do you care about rounding, or are you just rounding down?
Are you going smallest units to biggest units, or the other way around?
eg. smallest first:
5500ms / 1000 => 5 seconds

100000ms / 1000 => 100 seconds
100 seconds is bigger than 60 secs (in a minute), so count the number of minutes too.

Code would help

it doesn't matter i guess. as long it turns out like something like this 154:19:10 when the progarm is done. so it being hours:Minutes:S econds

[jca613]

mport java.util.*;
public class hw_6 {
public static void main(String[] args){
}

private static String convertMillis(l ong millis) {
System.out.prin t("How much Millseconds ");
long time = millis / 1000;
int seconds = ((int)(time % 60));
int minutes = ((int)((time % 3600) / 60));
int hours = ((int)(time / 3600));
return convertMillis(0 ) ;
}

private static final StringBuilder(S tring convertedTime){
return convertedTime.t oString();
StringBuffer sb = new StringBuffer();

sb.append(hours );
sb.append(":");
sb.append(minut es);
sb.append(":");
sb.append(secon ds);
String s = sb.toString();

}
{
}
}
this what i got so far? did i do something wrong? or am i missing something. and do i need to add a assert ..:..:..".equal s(convertMillis (....) into it?

This is good so far. Now you just need to organize your code to call each other properly.

private static String convertMillis(long millis) {
  ...
  ...
  int hours = ((int)(time / 3600));

  //create return string.
  StringBuffer sb = new StringBuffer();
  sb.append(hours);
  ...
  ...
  return sb.toString();
}

and in your main, you'd have something like (pseudocode):

public static void main(String[] args){
  System.out.println("How much Millseconds ");
  get millis from input.
  System.out.println(convertMillis(millis) );
}

[jca613]

import java.util.*;
public class hw_6 {

public static void main(String[] args){

System.out.prin tln("How much Millseconds ");

get millis; from input;


System.out.prin tln(convertMill is(millis) );
}
//return string

private static String convertMillis(l ong millis) {
StringBuffer sb = new StringBuffer();
sb.append(hours );
sb.append(":");
sb.append(minut es);
sb.append(":");
sb.append(secon ds);
return sb.toString();
long time = millis / 1000;

int seconds = ((int)(time % 60));
int minutes = ((int)((time % 3600) / 60));
int hours = ((int)(time / 3600));
return convertMillis(0 ) ;
}

private static final StringBuilder(S tring convertedTime){
return convertedTime.t oString();


}

i dont know if that is what you mean by more organized. i am still getting errors. for example.
private static final StringBuilder(S tring convertedTime){ <-- there it says i cant find the return string and stuff

i get errors on the pseudocode.

[jkmyoung]

In your convertMillis function, you're using hours before you set hours! Set the hours before you use it.

pseudocode: Not real, syntactically correct code. -> figure it out.

thanks well i got it done
