Find the maximum value and minimum value in milesTracker. Assign the maximum value to maxMiles, and the minimum value to minMiles. Sample output for the given program:

Min miles: -10 Max miles: 40

I have presently:

import java.util.Scanner;

public class ArraysKeyValue { public static void main (String [] args) { final int NUM_ROWS = 2; final int NUM_COLS = 2; int [][] milesTracker = new int[NUM_ROWS][NUM_COLS]; int i; int j; int maxMiles; // Assign with first element in milesTracker before loop int minMiles; // Assign with first element in milesTracker before loop

milesTracker[0][0] = -10; milesTracker[0][1] = 20; milesTracker[1][0] = 30; milesTracker[1][1] = 40; // Answer between these two comments

for(i = 0;i < NUM_ROWS; i++) { for( j=0;j < NUM_COLS; j++) { if(milesTracker[i][j] > maxMiles) maxMiles = milesTracker [i][j]; if(milesTracker[i][j] < minMiles) minMiles = milesTracker[i][j]; } }

//Answer between these two comments

System.out.println("Min miles: " + minMiles); System.out.println("Max miles: " + maxMiles); } }

And am getting the following errors:

ArraysKeyValue.java:23: error: variable maxMiles might not have been initialized if(milesTracker[i][j] > maxMiles) ^ ArraysKeyValue.java:25: error: variable minMiles might not have been initialized if(milesTracker[i][j] < minMiles) ^ ArraysKeyValue.java:30: error: variable minMiles might not have been initialized System.out.println("Min miles: " + minMiles); ^ ArraysKeyValue.java:31: error: variable maxMiles might not have been initialized System.out.println("Max miles: " + maxMiles); ^ 4 errors

Please help!
