Answer:
Variable
Explanation:
I'll answer this question in computing terms.
The answer to this question is a variable. Variable can be seen as memory location or spots.
They can be compared to the containers (in real world). Variables are used to store values same way containers are used to store contents.
In computing, a variable must have a
Answer:
The following program are:
public class Value { // Define a class named Value which is public type
private boolean modified = false; // a Boolean instance variable named 'modified',
private int val;
public Value(int i) { val = i; }
public int getVal() { return val; }
public void setVal(int i) { val = i; modified = true; }
public boolean wasModified() { return modified; }
}
Explanation:
Firstly, a class defines "Value" and then take a Boolean variable "modified" initialize the value false and then take an integer variable "val" and after that we create a constructor taking a parameter in which variable is assigned to the "val" and then we create an integer type function "getVal()" which returns the value of the "val", and then we create a void type function "setVal()" which takes parameter assign to the value to the "val" and we set the value in the "modified" is true and after all we create a Boolean type function, "wasModified()" which give an output true, if the function "setVal()" was called
