<div class="pre" style="margin: 0; padding: 0; font-family: monospace">Hi,all <br /> I want to combine two method (method1 and method2) into another method3, </div>
<div class="pre" style="margin: 0; padding: 0; font-family: monospace">
<ul>
<li>All these methods share same name, and parameters, but in different classes.</li>
</ul>
</div>
<div class="pre" style="margin: 0; padding: 0; font-family: monospace"> I use method 'importBodyContentsFrom' to create method3's body using method1, but when I use this function to import method2's body to method3, it incurs problem "<span style="color: #ff0000;">java.lang.IllegalArgumentException: value may not be null</span>". Is that a right way of using it? Or, any other suggestions for my work? </div>
<div class="pre" style="margin: 0; padding: 0; font-family: monospace"> Thanks in advance.</div>
