Java Exercises: Count the two elements of two given arrays of integers with same length, differ by 1 or less
Java Basic: Exercise-100 with Solution
Write a Java program to count the two elements of two given arrays of integers with same length, differ by 1 or less.
Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.*;
import java.io.*;
public class Exercise100 {
public static void main(String[] args)
{
int[] array_nums1 = {10, 11, 10, 20, 43, 20, 50};
int[] array_nums2 = {10, 13, 11, 20, 44, 30, 50};
System.out.println("Array1: "+Arrays.toString(array_nums1));
System.out.println("Array2: "+Arrays.toString(array_nums2));
int ctr = 0;
for(int i = 0; i < array_nums1.length; i++) {
if(Math.abs(array_nums1[i] - array_nums2[i]) <= 1 && array_nums1[i] != array_nums2[i])
ctr++;
}
System.out.printf("Number of elements: "+ctr);
System.out.printf("\n");
}
}
Sample Output:
Array1: [10, 11, 10, 20, 43, 20, 50] Array2: [10, 13, 11, 20, 44, 30, 50] Number of elements: 2

How to sort an ArrayList?
Collections.sort(testList); Collections.reverse(testList);
That will do what you want. Remember to import Collections though!
