数组元素的赋值和遍历数组

package 数组元素赋值和遍历数组;

import java.util.Scanner;

public class 赋值遍历 {

public static void main(String[]args)

{

Scanner in = new Scanner(System.in);

int[] a;//先定义

a = new int[5];//后赋值

int c[]={2,8,6,9,5,4,7};//定义的时候赋值

for(int i=0;i<5;i++)

{

a[i] = in.nextInt();

}

for(int j=0;j<a.length;j++)//a的length的属性是数组元素个数

{

}

System.out.println();

for(int j=0;j<c.length;j++)

{

System.out.print(+c[j]+" ");

}
