Question

Java语言new数组怎么从键盘里获取长度再循环输入，怎么来实现

Answer 1

import java.util.Scanner;

public class Test {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int length = 0;
        System.out.println("请输入数组长度：");
        if (scanner.hasNext()) {
            length = scanner.nextInt();
        }

        int[] arrays = new int[length];
        System.out.println("数组总长度为"+length);
        for (int i = 0; i < length; i++) {
            int temp = scanner.nextInt();
            arrays[i] = temp;
            System.out.println("arrays["+i+"]已设置完毕");
        }
        System.out.println("****输入完毕，数组为：");
        for(int z:arrays){
            System.out.println(z);
        }
    }
}
