passing array to method

[deva1]

public class example {
int i[] = {0};
public static void main(String args[]) {
int i[] = {1};
change_i(i);
System.out.println(i[0]);
}
public static void change_i(int i[]) {
int j[] = {2};
i = j;
}
}

when I run this program I get 1 .but my question is

what is the result of i=j; why it is not changing the value of i[] in the main method.


thanks

The scope of array j is within the method change_i, so array i reference to array j is useless. We cannot reference to a local literal or object outside their method.

public class example {
static int i[] = {0};
public static void main(String args[]) {
int i[] = {1};
change_i(i);
System.out.println(i[0]);
}
public static void change_i(int i[]) {
int j[] = {2};
i[0] = j[0];
}
}

// avoid to use same variable name for different scope
public class example {
public static void main(String args[]) {
int i[] = {1};
change_i(i);
System.out.println(i[0]);
}
public static void change_i(int i[]) {
int j[] = {2};
i[0] = j[0];
}
}

deva1 :

Why have you posted the same question in two different threads in the same forum (see deva1's previous post) ?
