How to call blocks from other classes?

Non static blocks & Static blocks are executed one by one by the order of their defintion before any constructor is being executed.

Static blocks can also be invoked without creating instance of the Class(without actually calling constructors) by simply loading the Class.


Class.forName("ClassThatContainsStaticBlock");

class ExOne{

//Static block
static{
System.out.println("This is static block of ExOne");
}

//Non static block
{
System.out.println("This is non-static block of ExOne");
}

public ExOne(){
System.out.println("This is Constructor block of ExOne");

}
}

public class ExOneTest{

public static void main(String[] args) {
try {
// Static blocks can be called either by creating
// new instance or loading the class
new ExOne();
Class.forName("ExOne");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
