public class shuzu { public void shuzu1(int[]arr) { Scanner sc=new Scanner(System.in); for(int i = 0;i<arr.length;i++) { System.out.println((i+1)+"個數(shù)"); arr[i+1]=sc.nextInt(); for(int n:arr) { System.out.println(arr); }} } public static void main(String[] args) { // TODO Auto-generated method stub shuzu a=new shuzu(); int[]arr2 = a.shuzu1(int[]arr); }}
怎樣創(chuàng)建數(shù)組，然后從鍵盤輸入數(shù)字？
