Both will be execute when you create an object. At first the instance block and then the constructor. A constructor can get values. For example: public myClass(int num){ this.num = num; } In an instance block you could do this: { num = 7; } But without an constructor it is not possible to create an object with a specific value. You would need to write a setter for int num and to call this method. //with constructor MyClass my = new MyClass(4); //without constructor MyClass my = new MyClass(); my.setNum(4); Here is a code about static and instance block: https://code.sololearn.com/cRKxAwr2rE6t/?ref=app
