java怎样输出数组中的前n个元素?

Answer 1

import java.util.*;

public class Test {
public static void main(String[]args){
int[] arry = new int[]{1,2,3,4,5,6,7,8,9,0,2,4,3,6,5,9,6,5};
//这个数组是您自己定义的，有多少元素自己写就好
Scanner input =new Scanner(System.in);
System.out.println("请输入你想要输出，数组前几个元素：");
int a=input.nextInt();
if(a > arry.length){
System.out.println("个数大于数组长度");
}else{
for(int i = 0; i < a; i++){

System.out.print(arry[i]);
System.out.print(" ");
}

}
}
}
