Question

In Java all classes are loaded into the JVM dynamically, upon the first use of a class.

Does it mean if i have class in a my source file and I do not make any reference to it then its Class object is not created (i.e. .class file is not created)?

In the sample code below iam not making a refernce to test3 class but still its class object gets created.

class test1 {
    static {
        System.out.println("static block of test1");
    }
}   
class test2{
    static {
        System.out.println("static block of test2");
    }
}
class test3 {}
class MyExample1 {
    public static void main(String ...strings ) {
    new test1();
    new test2();
    }
}

Why test3.class file gets created?

Answer 1

.class file was created at compilation time. But, it will be loaded from .class file by first usage (probably).

From where it should be loaded without .class file?)
