When is it OK to create object of a class inside a method of that class?

Question

public class TestClass(){
    public static void main(String []args) {
        TestClass t1 = new TestClass();
        t1.anything();
    }
}

Is it not

Answer 1

You would only have an infinite loop (stack overflow error) if you tried to do the below:

public class TestClass {
    public TestClass() {
        TestClass t = new TestClass();
    }
}

And elsewhere, you try to create an object of the class TestClass.
