a question about static clause

[Steven Gao Song]

public class Static {

static
{
int x = 5;
}
static int x, y;

public static void main(String[] args) {

x--;
myMethod();
System.out.println(x + y + ++x);
}

public static void myMethod()
{
y = x++ + ++x;
}
}

I cannot understand why "int x = 5;" is not executed.
Thank you.

I cannot understand why "int x = 5;" is not executed.


The Static block is executed i.e. int x = 5 is executed
but int x declared in the static block is local to the block
hence it has no effect on / is not related to the static variable x.

   
 public class Static {
 
static
{
int x = 5; // local to the block
}
static int x, y; //default values assigned i.e. 0
 
public static void main(String[] args) {
 
x--; x is -1
myMethod();
System.out.println(x + y + ++x); // 1 + 0 + 2 =3
}
 
public static void myMethod()
{
y = x++ + ++x; //-1 + 1 = 0
}
}

The static block is executed and a local int variable is set to 5.

I got it. Thanks a lot.
