Complete the code for the following program. You are provided with an abstract class called abst. Create a class that will be a child of abst and it will be called usesAbst. Your program will have an int variable called value, and all the appropriate methods, as well 2 constructors. The first constructor will simply set the variable value to 0. The second constructor will set the variable value to equal a passed in parameter. You do not have to comment your code. public abstract class abst{ public abst () { } //Outputs to the screen the message Hello public abstract void sayHello (); //returns the stored int value public abstract int getValue (); //sets the int value to x public abstract void setValue (int x); //Outputs to the screen the message Another method public void output () { System.out.println("Another method"); public String tostring () { return "This is an abstract class"; }
Novice: How can i access a main class objects from outside the function? / Better Alternative? If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber.  What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that. i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.
a. Instance of a class is called, functions have same name but different sets of parameters.
