When we talk about instance variables, the default initial value for a numeric variable is always '0'. Any other variable in your code must be initialized before you can use it.
public class MyClass{
public int x; // 0 by default
public float y: // 0 by default
public MyClass{
int z;
z++; // Error 'z' don't have a default value
}
}
