/* 1. Case-1> Valid Signature

*

* i) public void methodName(int... x)

* ii)public void methodName(int ...x)

* iii)public void methodName(int...x)

*

* 2. Case-2>We can mix normal argu. with var-arg but var-arg must be always last.

*

* i) public void methodName(int... x, int y) //Invalid

* ii) public void methodName(String s,int... x)// valid

* iii)public void methodName(int x,int...y) ///valid

*

* 3. Case-3> In an argument list there should be only one var arg

*

* i) public void methodName(int y, int...z) //valid

* ii) public void methodName(int...x , int... y) //invalid

*

* 4. Case-4> We can overload var arg method but var arg method will get a call only if none of

* matches are found. (just like default statement of switch case.)

*

* 5. Case-5> No two same signature method can me exist in one class

* eg:

* public void m1(int... x) --->internally--> m1(int[] x)

* public void m1(int[] x)

*

* both method signature is same and hence they can not exist in same class at a same time

*

* Note:

* i)Whereever SingleDimension array is present we can replace it with var arg.

* eg: public static void main(String[] arg)---> (String... arg)

*

* ii)Whereever var arg is present we can not replace it with SingleDimension array/

* eg:public void add(int... x)---> (int[] x)-->invalid

*

*

* Because:

* m1(int... x)=> we can call to this method by passing group of int values or 1D array and

* x will become 1D array internally (int[] x)

* m1(int[] x)=> we can call to this method by passing 1D array only.

/*

* Note:

* To accept the multiple arguments of 1D array then we have to make the ellipse of 1D array

* eg: public void methodName(int[]... x)--->internally(int[][] x)

* {

* public void m1(int[]... x)

* {

* for(int[] i:x)
