新手问题，帮我看看怎么输出。

Question

public class Array1
{
   public static void main(String[] args)
    {
    int []a=new int[5];
    int i;
    for( i=0;i<a.length;i++)
         {
         a[i]=i+1;
         }
         System.out.println("数组各个元素:"+a[i]);
        
    }
   
   
    }
} 
我想输出数组的各个元素，可是
最后有异常，那到底怎才能输出啊？

Answer 1

int []a=new int[5];只是为数组分配一个空间，还需要为每个元素分配一个空间

Answer 2

public class Array1
{
   public static void main(String[] args)
                   {
                   int []a=new int[5];
                   int i=0;
                   for( i=0;i<a.length;i++)
                           {
                               a[i]=i+1; 
                               System.out.println("数组各个元素:"+a[i]);                           }
                                                     
                   }
                   
                   
               }
} 
输出结果为：数组各个元素：1
          数组各个元素：2
          数组各个元素：3
          数组各个元素：4
          数组各个元素：5

Answer 3

public class Array1
{
   public static void main(String[] args)
                   {
                   int []a=new int[5];
                   int i;
                   for( i=0;i<a.length;i++)
                           {
                               a[i]=i+1;   
                            System.out.println("数组各个元素:"+a[i]);
 
                           }
                                                     
                   }
                   
                   
               }
} 

Answer 4

public   class   Array1 { 
    public static void main(String[] args) { 
                 int   []a=new   int[5]; 
                 int   i=0; 
                     for(   i=0;i <a.length;i++){ 
                                          a[i]=i+1;   
                                          System.out.println( "数组各个元素: "+a[i]);                       } 
                                                                                                          
     } 
                                      
                                      
                          
}   
输出结果为：数组各个元素：1 
                    数组各个元素：2 
                    数组各个元素：3 
                    数组各个元素：4 
                    数组各个元素：5
