// Lab1.java STARTER FILE
import java.io.*; // I/O
import java.util.*; // Scanner class
public class Lab1
{
public static void main( String args[] ) throws Exception
{
final double MILES_PER_MARATHON = 26.21875;
Scanner kbd = new Scanner (System.in);
double aveMPH=0, aveMinsPerMile=0, aveSecsPerMile=0;
System.out.print("Enter marathon time in hrs minutes seconds: ");
//要在这里加入几段代码
System.out.println();
System.out.format("Average MPH was: %.2f mph\n", aveMPH );
System.out.format("Average mile split was %.0f mins %.1f seconds per mile", aveMinsPerMile, aveSecsPerMile );
System.out.println();
}
}
如果要使上面这段代码最后输出成如图所示, 该怎么就添加代码呢
