Let's say you have this method in a java class:<div><br></div><div>public void addOne(int number){</div><div> number = number +1;</div><div>}</div><div><br></div><div><br></div><div>And let's say you want to invoke that method from another method in the same (or a different. It doesn't matter) object:</div>
<div><br></div><div>int number = 0;</div><div>this.addOne(number);</div><div>System.out.println("Number= "+number);</div><div><br></div><div>What is the output of the code above? Figure out that and you will figure out what is happening with your global.</div>

<br>
in the rule2, the value of the global variable "count" must be 1, why m i<br>
getting it as zero ?<br>
