如何用循環(huán)向數(shù)組中輸入數(shù)據(jù)并最終顯示出來
import java.util.Scanner;
public class Test{
?public static void main(String[] args){
??Scanner input=new Scanner(System.in);
??int[] stu;
??stu=new int[3];
??int i = 0;
??for(i=0;i<stu.length;i++){
???System.out.print("請(qǐng)輸入第"+i+"個(gè)值：");
???int stu1=input.nextInt();
???stu[i]=i;
??}
??
??System.out.println("str="+stu[i]);
?}
}
//這個(gè)代碼是錯(cuò)誤的，如何用循環(huán)的方式依次向stu數(shù)組輸入數(shù)據(jù)并最終輸出呢？

import?java.util.Arrays; import?java.util.Scanner; public?class?Test?{ public?static?void?main(String[]?args)?{ Scanner?input?=?new?Scanner(System.in); int[]?stu?=?new?int[3]; for?(int?i?=?0;?i?<?stu.length;?i++)?{ System.out.print("請(qǐng)輸入第"?+?(i+1)?+?"個(gè)值："); int?stu1?=?input.nextInt(); stu[i]?=?stu1; } System.out.println("str="?+?Arrays.toString(stu)); } }此為正確代碼
