Question
Code must be in java.
Create a class Int with the following components: a. A field to store an int value. b. A constructor so that new Int (x) creates an Int object that stores the int value x. c. An instance method toString so that x.toString () returns the value of the Int object x in String form. d. An instance method plus so that x.plus (y) returns a new Int object whose value is the value of the Int x plus the value of the Int y. There should be no side effects. e. Instance methods minus, times, and div, similar to the plus method described above. (The div method should perform integer division, like the/operator on int values.) f. An instance method isPrime so that x.isPrime () returns true if the value of the Int x is a prime number. In some object-oriented languages, like Smalltalk, absolutely everything is an object-integers, booleans, characters, strings, everything. In such languages, arithmetic really works a bit like this exercise, though the language may provide a more natural syntax for operators.Explanation / Answer
Int.java
public class Int {
//Declaring instance variable
private int x;
//Parameterized constructor
public Int(int x) {
super();
this.x = x;
}
//getters and setters
public int getX() {
return x;
}
public void setX(int x) {
this.x = x;
}
//This method will add two numbers
public Int plus(Int y) {
x = x + y.getX();
Int z = new Int(x);
return z;
}
//This method will subtract two numbers
public Int minus(Int y) {
x = x - y.getX();
Int z = new Int(x);
return z;
}
//This method will divide two numbers
public Int div(Int y) {
x = x / y.getX();
Int z = new Int(x);
return z;
}
//This method will multiply two numbers
public Int times(Int y) {
x = x * y.getX();
Int z = new Int(x);
return z;
}
//This method will check whether the number is prime or not
public boolean isPrime() {
// If the user entered number is '2' return true
if (x == 2)
return true;
for (int i = 2; i * i <= x; i++) {
if (x % i == 0)
return false;
}
return true;
}
//toString method is used to display the contents of an object inside it
@Override
public String toString() {
return "Int [x=" + x + "]";
}
}

_____________________
Output:
Enter an Inter value of x :45
Enter an Inter value of y :5
Int [x=50]
Int [x=45]
Int [x=9]
Int [x=45]
5 is a Prime Number
