In this tutorial, we will learn Overriding concept in java with example
Overriding is a feature that allows a child class to override a method which is present in parent class
We should have same method signature of parent class
Example
<span class="token keyword">class</span> <span class="token class-name">SuperClass</span> <span class="token punctuation">{</span>
<span class="token keyword">public</span> <span class="token keyword">void</span> <span class="token function">print</span><span class="token punctuation">(</span><span class="token class-name">String</span> printText<span class="token punctuation">)</span> <span class="token punctuation">{</span>
