static and instance initialization blocks

[Rajiv Rai]

package com.rajiv;

public class SmallInit {
	
	static int x;
	int y;
	
	static {
		x = 7;
		//y = 4;
	}
	
	{
		y = 8;
		x = 17;
	}

}

Why does line 10 throw a compiler error
whereas line 15 does not?

As per me if line 10 throws an error due to the
static issue , its the same case for line 15


Thanks

no, they are not same case . initializer tutorial (<-- click)

Line 15 will assign 17 to the static variable x every time a new instance of the class is created. While kind of an odd thing to want to do, it is a logical possibility.
Line 10 does not make sense, the static initializer runs when the class is loaded into memory, an instance does not have to be created and y is an instance variable.
