You can do this

Public consName(){
     super("myName")
     this.age = 5
}

Public consName(){
     super("myName")
     this.age = 5
}

The age variable is only accessible through the any object of the child class (subclass) only and not in any object of the parent class

Say I have two constructors, and the first constructor does not have super() defined, but it has a this statement defined, will it run the next Constructor?

If you have multiple methods in the same class with the same name, which method will run depends on which order of parameters you gave so lets say this:

Class child extends parent{
      public child(String name){
            super(name);
      }

       Public child(int age){
            this.age = age;
}

Class child extends parent{
      public child(String name){
            super(name);
      }

       Public child(int age){
            this.age = age;
}

Now if i did this: Child myChild = new Child("NAME"); the first constructor will work How ever if i did this: Child otherChild = new Child(8); The second constructor will run Sorry typing is not the best and im slown im just on phone

So if u have multiple methods with the same name which one will run depends on you order the arguments in the constructor call or method call I recommend learning through codecademy's learn java course
