Examples are as follows:
package org.company.project.test;
import java.util.Arrays;
import java.util.Scanner;
public class ArraysDelete { public static void main(String[] args) {
// Delete something from the array 1 Method of element:
// The final 1 Instead of the specified element, the array is shrunk
Scanner sc =new Scanner(System.in);
int[] arr = new int[]{1,2,4,5,9,8,0};
System.out.println(Arrays.toString(arr));
System.out.println(" Please enter the number of elements to delete: ");
int n = sc.nextInt(); sc.close();
// The final 1 Element replaces the specified element
arr[n-1] = arr[arr.length-1];
// Array shrinkage capacity
arr = Arrays.copyOf(arr, arr.length-1);
System.out.println(Arrays.toString(arr));
} }
Operation results:
[1, 2, 4, 5, 9, 8, 0]
Please enter the number of elements to delete:
