Question

Given this class.

class Test {
into a;
Test(into i) { a = I}
}

write a method called swap() that exchanges the contents of the objects referred to by two Test object references.

Answer 1

public static void swap(Test T1, Test T2) {
int buf = 0;
buf = T1.a;
T1.a = T2.a;
T2.a = buf;
}

Not hard, huh?

Answer 2

very good sir.. well done here is my version:

void swap(Test ob1, Test ob2) {
into t;

t = ob1.a;
ob1.a = ob2.a:
ob2.a = t;
}
