 <p>如上图，在方法内定义的变量直接存储在栈中</p>

 <p>当我们写“int age=50；”，其实是分为两步的：</p>
-<pre class="language-java" data-language="java"><code class="language-java"><span class="token number">1</span>int age<span class="token punctuation">;</span><span class="token comment">//定义变量</span>
-<span class="token number">2</span>age<span class="token operator">=</span><span class="token number">50</span><span class="token punctuation">;</span><span class="token comment">//赋值</span></code></pre>
+<pre class="language-java" data-language="java"><code class="language-java"><span class="token keyword">int</span> age<span class="token punctuation">;</span><span class="token comment">//定义变量</span>
+age<span class="token operator">=</span><span class="token number">50</span><span class="token punctuation">;</span><span class="token comment">//赋值</span></code></pre>
 
 <p>首先JVM创建一个名为<code>age</code>的变量，存于局部变量表中，然后去栈中查找是否存在有字面量值为<code>50</code>的内容，如果有就直接把<code>age</code>指向这个地址，如果没有，JVM会在栈中开辟一块空间来存储<code>50</code>这个内容，并且把<code>age</code>指向这个地址。因此我们可以知道： <strong>我们声明并初始化基本数据类型的局部变量时，变量名以及字面量值都是存储在栈中，而且是真实的内容。</strong></p>
 <p>我们再来看<code>int weight=50;</code>，按照刚才的思路：字面量为<code>50</code>的内容在栈中已经存在，因此<code>weight</code>是直接指向这个地址的。由此可见：<strong>栈中的数据在当前线程下是共享的</strong>。</p>
