Complete the constructors of the following class using constructor chaining where possible. The class represents a student number. A student number is an integer value greater than 999999. Internally, the class uses a string to store the digits of the student number because there are many operations that might be performed on a student number where it is easier to manipulate a string compared to manipulating an integer value. public class StudentNumber { private String number; // Initializes this student number to the specified number. // Throws an IllegalArgumentException if number is less than 999999 public StudentNumber(int number) { } // initializes this temperature by copying another temperature public StudentNumber(StudentNumber other) { } }

Given :

public class StudentNumber { private String number;

// Initializes this student number to the specified number. // Throws an IllegalArgumentException if number is less than 999999 public StudentNumber(int number) {

}

// initializes this student number by copying another student number public StudentNumber(StudentNumber other) {

}

}
