package com.bini.babu;

public class ObjectRefernceInStaticBlock {

static {
	ObjectRefernceInStaticBlock orsb = new ObjectRefernceInStaticBlock();
	System.out.println(orsb);
}
public static void main(String[] args) {

}

}

Output

com.bini.babu.ObjectRefernceInStaticBlock@378fd1ac

In the above code the 'orsb' variable is created as an instance and the variable 'orsb' prints the address location where the ObjectRefernceInStaticBlock is allocated.

package com.bini.babu;

public class StaticReference { static StaticReference sr;

static {
	   System.out.println(sr);
	   sr = new StaticReference();
}
public static void main(String[] args) {
    System.out.println(StaticReference.sr);
}

}

Output

null com.bini.babu.StaticReference@378fd1ac

In the above code we globally created a static variable sr and in the static block we printed sr bu the output is 'null' because after printing new line (i.e System.out.println(sr);) we are creating an object reference (i.e sr = new StaticReference();). Hence sr will get the address location, that why the second line of output is 'com.bini.babu.StaticReference@378fd1ac'.
