Difference between static and init block

The static block is only loaded when the class object is created by the JVM for the 1st time whereas init {} block is loaded every time class object is created. Also first the static block is loaded then the init block.

public class LoadingBlocks {

    static{
        System.out.println("Inside static");
    }
    
    {
        System.out.println("Inside init");
    }
    public static void main(String args[]){
        new LoadingBlocks();
        new LoadingBlocks();
        new LoadingBlocks();
    }
}

Output:

Inside static
Inside init
Inside init
Inside init

So static block is initialized only once, that is it is per class basis, whereas init block is per object basis.
