Java Parameters

Given the method:

public void swap (int iOne, int iTwo) {

System.out.println (iOne, + “, “, + iTwo); // line a

int iTemp = iOne;

iOne = iTwo;

iTwo = iTemp;

System.out.println (iOne, + “, “, + iTwo); // line b

} // of swap

Then, executing the code fragment:

int iThis = 5;

int iThat = 6;

System.out.println(iThis, + “, “, + iThat); // line c

swap (iThis, iThat);

System.out.println(iThis, + “, “, + iThat); // line d

Gives the output:

5, 6 ( from fragment line c )

5, 6 ( from swap line a )

6, 5 ( from swap line b )

5, 6 ( from fragment line d )
