Hello, im new to programming, and im learning how, but i wanted to try to make some sort of program that will tell you how long you are at a place, such as work or school.
I call it the "School Calculator"
So it works like this:
You enter when your school starts, lets say 4
You enter when your school ends, lets say 530
You enter weather this is AM or PM, lets say there both PM
It will then tell you:
"You school is 1 hour, 30 minutes long."
Now i coded this almost perfuctly, it will tell you this, but it will put everything as just a regular number, like "Your school is 130 hours long"
So I relised im going to need some sort of 24-hour clock, so that i can brake it into minutes.
Can anyone tell me how to:
Make it treat every number as "time" and once it reaches 60 minutes, it turns into 1 hour, after it will display the 60 minutes section (the hours) into a diffrent catagory, so it will say in the code "your school is" + hours + " and " + minutes + "long"
Here is my code for this school calculator:
import java.io.BufferedReader;
import java.io.InputStreamReader;

}

}

}

}

{

writeLine ("");
write ("When does your school start: ");
time1 = readInt ();
writeLine ("");
writeLine ("AM or PM?");

if(time1>59){
time1++;
}
write ("When does your school end: ");
time2 = readInt ();
answer = time2 - time1;
writeLine ("AM or PM?");
timeframe = readChar ();
writeLine ("Your school is: " + answer + " hours long.");
writeLine ("*This program is in debug mode, and is still being worked on*");
