How to pass mutable objects by value to java
<p>Is there any way that I can pass mutable Objects by value to a function in java?</p>

<p>What I actually want is to pass an object to a method, do some operations on it (change it) and again call that method with that old object only(not the changed value). </p>

<p>here is some sample:</p>

<pre><code>    { MyObj obj = new MyObj(); obj.setName("name");

    append(obj); 
    System.out.println(obj.name);

    prepend(obj); 
    System.out.println(obj.name);

    }

    void append(MyObj obj){ obj.name+="1"; }

    void prepend(MyObj obj){ String a = "1"; obj.name=a+obj.name; }
</code></pre>

<p>At the end of this code, I want output as:</p>

<pre><code>name1
1name
</code></pre>
