List is an interface, and you can not initialize an interface. Instantiate an implementing class instead.

blocks|key|1136512|text|列表是一个接口，您不能实例化一个接口，因为接口是一个约定，哪些方法应该有您的类。为了实例化，您需要实现(实现)该接口。尝试下面的代码，并使用非常流行的列表接口实现：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1136513|List<String>+supplierNames+=+new+ArrayList<String>();+|code-block|syntax|javascript|1136514|或|1136515|List<String>+supplierNames+=+new+LinkedList<String>();|1136516|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

List is an Interface, you cannot instantiate an Interface, because interface is a convention, what methods should have your classes. In order to instantiate, you need some realizations(implementations) of that interface. Try the below code with very popular implementations of List interface:

<pre><code>List&lt;String&gt; supplierNames = new ArrayList&lt;String&gt;(); 
</code></pre>

or

<pre><code>List&lt;String&gt; supplierNames = new LinkedList&lt;String&gt;();

List is just an interface, a definition of some generic list. You need to provide an implementation of this list interface. Two most common are:

ArrayList - a list implemented over an array

<pre><code>List&lt;String&gt; supplierNames = new ArrayList&lt;String&gt;();
</code></pre>

LinkedList - a list implemented like an interconnected chain of elements

<pre><code>List&lt;String&gt; supplierNames = new LinkedList&lt;String&gt;();

If you check the <a href="https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/List.html" rel="noreferrer">API</a> for <code>List</code> you'll notice it says:
<pre><code>Interface List&lt;E&gt;
</code></pre>
Being an <code>interface</code> means it cannot be instantiated (no <code>new List()</code> is possible).
If you check that link, you'll find some <code>class</code>es that implement <code>List</code>:
<blockquote>
All Known Implementing Classes:
<code>AbstractList</code>, <code>AbstractSequentialList</code>, <code>ArrayList</code>, <code>AttributeList</code>, <code>CopyOnWriteArrayList</code>, <code>LinkedList</code>, <code>RoleList</code>, <code>RoleUnresolvedList</code>, <code>Stack</code>, <code>Vector</code>
</blockquote>
Some of those can be instantiated (the ones that are not defined as <code>abstract class</code>). Use their links to know more about them, I.E: to know which fits better your needs.
The 3 most commonly used ones probably are:
<pre><code> List&lt;String&gt; supplierNames1 = new ArrayList&lt;String&gt;();
 List&lt;String&gt; supplierNames2 = new LinkedList&lt;String&gt;();
 List&lt;String&gt; supplierNames3 = new Vector&lt;String&gt;();
</code></pre>
<hr />
Bonus: 
You can also instantiate it with values, in an easier way, using the <code>Arrays</code> <code>class</code>, as follows:
<pre><code>List&lt;String&gt; supplierNames = Arrays.asList(&quot;sup1&quot;, &quot;sup2&quot;, &quot;sup3&quot;);
System.out.println(supplierNames.get(1));
</code></pre>
But note you are not allowed to add more elements to that list, as it's <code>fixed-size</code>.

JDK 7 and later you can use the diamond operator

Just in case, any one still lingering around this question. Because, i see one or two new users again asking the same question and everyone telling then , No you can't do that, Dear Prudence, Apart from all the answers given here, I would like to provide additional Information - 
Yes you can actually do, List list = new List();
But at the cost of writing implementations of all the methods of Interfaces. 
The notion is not simply List list = new List(); but 

<pre><code>List&lt;Integer&gt; list = new List&lt;Integer&gt;(){

 @Override
 public int size() {
 // TODO Auto-generated method stub
 return 0;
 }

 @Override
 public boolean isEmpty() {
 // TODO Auto-generated method stub
 return false;
 }

 @Override
 public boolean contains(Object o) {
 // TODO Auto-generated method stub
 return false;
 }
</code></pre>

..... and So on (Cant write all methods.)

This is an example of Anonymous class. Its correct when someone states , No you cant instantiate an interface, and that's right. But you can never say , You CANT write List list = new List(); but, evidently you can do that and that's a hard statement to make that You can't do.

We created <a href="https://github.com/thedocs-io/soyuz-to" rel="nofollow noreferrer">soyuz-to</a> to simplify 1 problem: how to convert <code>X</code> to <code>Y</code> (e.g. <code>String</code> to <code>Integer</code>). Constructing of an object is also kind of conversion so it has a simple function to construct <code>Map</code>, <code>List</code>, <code>Set</code>: 

<pre class="lang-java prettyprint-override"><code>import io.thedocs.soyuz.to;

List&lt;String&gt; names = to.list("John", "Fedor");
</code></pre>

Please check it - it has a lot of other useful features

Instead of :
<pre><code>List&lt;String&gt; supplierNames = new List&lt;String&gt;();
</code></pre>
Write this if you are using latest JDK:
<pre><code> List&lt;String&gt; supplierNames = new ArrayList&lt;&gt;();
</code></pre>
It's the correct way of initializing a List.

I can not initialize a List as in the following code:

<pre><code>List&lt;String&gt; supplierNames = new List&lt;String&gt;();
supplierNames.add("sup1");
supplierNames.add("sup2");
supplierNames.add("sup3");
System.out.println(supplierNames.get(1));
</code></pre>

I face the following error: 

<blockquote>
 Cannot instantiate the type <code>List&lt;String&gt;</code>
</blockquote>

How can I instantiate <code>List&lt;String&gt;</code>?
