要提取数组中的不同值,您需要将数组中的每个元素与其余所有元素进行比较,如果匹配,则得到重复的元素。为此,一种解决方案是您需要使用两个循环(嵌套),其中内部循环以i + 1开头(其中i是外部循环的变量),以避免重复。
import java.util.Arrays; import java.util.Scanner; public class DetectDuplcate { public static void main(String args[]) { Scanner sc = new Scanner(System.in); System.out.println("Enter the size of the array that is to be created::"); int size = sc.nextInt(); int[] myArray = new int[size]; System.out.println("Enter the elements of the array ::"); for(int i=0; i<size; i++) { myArray[i] = sc.nextInt(); } System.out.println("The array created is ::"+Arrays.toString(myArray)); System.out.println("indices of the duplicate elements :: "); for(int i=0; i<myArray.length; i++) { for (int j=i+1; j<myArray.length; j++) { if(myArray[i] == myArray[j]) { System.out.println(j); } } } } }
Enter the size of the array that is to be created :: 6 Enter the elements of the array :: 87 52 87 63 41 63 The array created is :: [87, 52, 87, 63, 41, 63] indices of the duplicate elements :: 2 5
