Question

We have a list of runner and their running time, write a program in Java to show the fastest runner and their time.

Answer 1

public class Main
{
        public static void main(String[] args) {
        
        //initialize array of names
         String[] names = {
                "Alexa", "Lilly", "Sharon", "Emma", "Joey", "Matt",
                "phoebe", "Jack", "David", "James"};
    
        //initialize array of running time ffor each runner
        int[] runningtime = {
                402, 341, 388, 278, 329, 445, 341, 273, 334, 500};

        //initialoze temp to 0
        int temp = 0;
        for (int i = 0; i < runningtime.length; i++) {
            
            /* fastest runner is the one who completes distance
            in minimum running time. find the minimum running time from the array 
            runningtime and store the index of minimum running time in temp variable.
            if running time of ith player is lower compare to first player 
            then temp becomes i. */
            if (runningtime[i] < runningtime[temp]) {
                temp = i;
            }
        }        
        
        //print the fastest runner as temp represents the index of the fastest runner
        System.err.println("Fastest runner: " + names [temp]);
        System.err.println( "Running Time of "+ names[temp] + ": " + runningtime[temp]);

    }

}

OUTPUT:
