You're trying to copy 8 items into an array of length 1. You can't do that.
From <a href="http://download.oracle.com/javase/6/docs/api/java/lang/System.html#arraycopy%28java.lang.Object,%20int,%20java.lang.Object,%20int,%20int%29" rel="noreferrer">the documentation</a>:
<blockquote>
Otherwise, if any of the following is true, an IndexOutOfBoundsException is thrown and the destination is not modified:
<ul>
<li>The srcPos argument is negative.</li>
<li>The destPos argument is negative.</li>
<li>The length argument is negative.</li>
<li>srcPos+length is greater than src.length, the length of the source array.</li>
<li>destPos+length is greater than dest.length, the length of the destination array.</li>
</ul>
</blockquote>
In this case, <code>destPos + length</code> is 8, and <code>dest.length</code> is 1, hence the exception is being thrown.
Note that arrays in Java have a fixed length. If you want an expandable container, look at <code>ArrayList</code>.

blocks|key|5232897|text|因为array的长度是1。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5232898|声明array[]+=+{+"NO+DATA+YET"+};创建了一个长度为1的数组，其中包含一项。|5232899|而是将目标数组声明为：|5232900|private+String+array[]+=+new+String[8];|code-block|syntax|javascript|5232901|entityMap^0|2|5|0|2|S|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|T|8|@$9|U|A|V|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|W|8|@]|D|@]|E|$]]|$1|J|3|K|5|L|7|X|8|@]|D|@]|E|$M|N]]|$1|O|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|P|$]]

Because the length of <code>array</code> is 1.

The declaration <code>array[] = { "NO DATA YET" };</code> creates an array of length 1 with one item in it.

Instead declare destination array as: 

<pre><code>private String array[] = new String[8];
</code></pre>

blocks|key|268664|text|数组的长度只有1，并且您正在尝试将8个元素从array2复制到数组中。尝试使用ArrayList或其他可以在需要时进行扩展的工具。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|268665|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

array only has a length of 1 and you're trying to copy 8 things into it from array2. Try using an ArrayList or something that will grow as you need it to grow.

SOLUTION TO ALL TYPES OF ARRAYINDEXOUTOFBOUNDS EXCEPTION:
Understand this with the help of following example facing ArrayIndexOutOfBoundsException:
<pre><code> public static void main(String [] args){
 String dest[] = { &quot;Iphone&quot;, &quot;Tutorials&quot;, &quot;Gallery&quot;, &quot;Android&quot;, &quot;item 1&quot;, &quot;item 2&quot;, &quot;item3&quot;, &quot;item 4&quot; };
 String src[]=new String[8];
 System.arraycopy(src, 0, dest, 1, src.length);
 System.out.println(dest[4]);
 }
</code></pre>
Solution to this above case can be any of the following:
1. Either increase the size of destination array so it could find a place.
2. Since we are starting from index 1 so you may copy only 7 elements from the source array.
3. Or you can start copying from index 0 in the destination array so it can accommodate all the array elements of source array.

System.arraycopy getting ava.lang.ArrayIndexOutOfBoundsException.. I am trying to copy data from one array to the next. but I am getting a exception

<pre><code>private String array[] = { "NO DATA YET" };


 private void setListData()
 {
 String array2[] = { "Iphone", "Tutorials", "Gallery", "Android", "item 1", "item 2", "item3", "item 4" };
 System.arraycopy(array2, 0, array, 0, array2.length);
 }
</code></pre>
