[英]I am trying to convert Java AES encryption to NodeJs. This is what I have tried so far
[英]I am trying to output the times in my code in hours and mins (00:00) and need help. This is what i have so far
我有我的代码,但是在解决方案3中,我希望将以分钟为单位的时间转换为小时和分钟(即,将341分钟转换为5小时41分钟)。
public class CityToSurf
{
//Method for lowest time index
private int getMinIndex(int[] times){
int minValue = times[0];
int minIndex = 0;//default value to start with
for(int counter=0;counter<times.length;counter++){
if(times[counter] < minValue){
minIndex = counter;
minValue = times[counter];
}
}
return minIndex;
}
public static void main (String[] arguments){
CityToSurf cs = new CityToSurf();
//create array of times and names
int[] times ={341,273,278,329,445,402,388,275,243,334,412,393,299,343,317,265};
String[] names ={"Elana","Thomas","Hamilton", "Suzie", "Phil","Matt", "Alex", "Emma", "John","James" ,"Jane", "Emily", "Daniel" ,"Neda", "Aaron", "Kate"};
//Solution 1
int fastestRunnerIndex = cs.getMinIndex(times);
System.out.println("Solution 1:");
System.out.println(names[fastestRunnerIndex]+ " "+ times[fastestRunnerIndex] );
//Solution 2
System.out.println("Solution 2:");
cs.getSortedArray(times, names);
//Solution 3
System.out.println("Solution 3:");
cs.timeConvert(times, names);
}
private void getSortedArray(int[] times, String[] names){
//store in a local variable the unchanged/old list
int[] oldTimes = new int[times.length];
for (int i=0;i<times.length;i++){
oldTimes[i] = times[i];
}
java.util.Arrays.sort(times);//sort the times from min to max times for the PLACEMENT
int place =1; //this is to initialize the placement for a list from 1 to 16.
//loop over my old times list and match the time in the old times with sorted times to find the corresponding index that will be used to get name and time
for (int i=0;i<times.length;i++){
//SORTED the min to max time from the list
int newSortedTime= times[i];
//loop over the sorted times to match the time
int oldIndex =0;
for (int j=0; j<oldTimes.length;j++){
int oldUnsortedTime = oldTimes[j];
if (oldUnsortedTime == newSortedTime){
oldIndex = j;
System.out.println(place + " " +names[oldIndex] + " " + oldTimes[oldIndex] );
place++;//increment to next placement
}
} }
}
private void timeConvert(int[] times, String[] names){
int[] oldTimes = new int[times.length];
int hours = times / 60; //since both are ints, you get an int
int minutes = times % 60;
System.out.printf("%d:%02d", hours, minutes);
}
}
times不是int,而是int [],因此这是行不通的。 我认为您正在寻找类似的东西:
private void timeConvert(int[] times, String[] names) {
for (int time : times) {
int hours = time / 60; //since both are ints, you get an int
int minutes = time % 60;
System.out.printf("%d:%02d\n", hours, minutes);
}
}
应该是这样的:
私有void timeConvert(int []次,String []名称){
int length = times.length ;
for(int i = 0;i<length;i++){
int hours = times[i] / 60;
int minutes = times[i] % 60;
System.out.printf("%d:%02d", hours, minutes);
}
}
