int intNumber = 123456789;
float floatNumber = intNumber;
int x = (int)floatNumber;
System.out.println(intNumber - x);
System.out.println(intNumber == x );

The order of initialization is like this:
Static variable/block(in superclass)==> static variable/block(in subclass)==>instance variable/block(in superclass)==>constructor(in superclass)==>instance variable/block(in sublcass)==>Finally the constructor in subeclass is executed..
