myClassObject is an instance of MyClass. What is printed when myClassObject.doSomething(2); is
run?
public class MyClass {
private int num;
}
O 25
public MyClass() {
num = 5;
O 52
}
public void doSomething (int num) {
}
an error will be thrown
none of these is correct
System.out.print(num);
System.out.print(this.num);
nothing because the MyClass class will not compile

What happens when "this" is used in a constructor's body to call another constructor of the same
class but the call is not the first statement in the constructor?
For example:
public Student (String name, String id) {
id;
}
this.id
this (name);
=
a runtime error
O a logic error (meaning the program will run without error, but not work correctly)
nothing happens- the program compiles and runs fine
O a compiler error
