Core Java - Interview Questions and Answers for 'Variable assignment' - 1 question(s) found - Order By Newest

 Q1. Why the following code produced this output ?

int x = 5;
int y = x;
y = 10;
      
System.out.println(x); // prints 5 and not 10
Core Java
Ans. Because when we say y = x, the value of x is copied to another memory location and then y points to that new memory location.

Unlike object references that once assigned point to same object in memory, value is copied in case of variable assignment.
