Array Doubts -

class GFC306 {
  static int[] i1 = {1}, i2 = {3};
  static void m1(int[] i1) {
    int[] i3 = i1; i1 = i2; i2 = i3;
  }
  public static void main (String[] args) {
    m1(i1);
    System.out.print(i1[0] + "," + i2[0]);
}}
 

i1 --------------> 1
 
i2 --------------> 3<-------------------|

    ||
inside m1 method:    ||

 i1 --------------> 1 <---------- i1(parm)
                            |
 i3 --------------->|

Whether muy digram is correct for the above pgm? If so,
why the line assignment i1 = i2 is described as i1(parm) points to i2 object instead of i1 points to i2.

Since the name i1 is same, it will behave like this always?..

And another query, how we can include diagrams(ms paint..or other)? the above diagram is painstacking...

Yes,it is hard to understand You can use MSVisio or any other of your choice.Save that and use Image tag.

class variable: i1, i2
local variable: i1, i3

m1(i1) -> i1(local) = i1(class)
inside m1():
i3 = i1(local) -> i3 = i1(class)
i1(local)=i2 -> don't care
i2=i3 -> i2 = i1(class)

so class variable i1 unchanged but i2 changed to i1, thus it "should" print out:

1 1

Hope it correct.
