from class:

AP Computer Science A

Definition

System.out.print() is a method in Java that allows you to display text or values on the console. It does not add a new line after printing.

congrats on reading the definition of System.out.print(). now let's actually learn it.

ok, let's learn stuff

Given the following code: ``` class A { public void display() { System.out.print("A"); } } class B extends A { public void display() { System.out.print("B"); } } class C extends B { public void display() { System.out.print("C"); } } ``` What will be the output when the following code is executed? ``` B obj1 = new C(); C obj2 = new C(); A obj3 = new C(); obj1.display(); obj2.display(); obj3.display(); ```
