Need help with the following Java program.

Class name Fraction.java

• Fraction has only 2 inputs of integers : numerator and denominator.
• Programmers must provide all necessary constructors for users. In the new type Fraction, there are the following cases:
  1. Fraction(int n, ind d) where n and are inputted.
  2. Fraction(int n) //only one parameter
  3. Fraction() //No parameter
  4. Fraction(String s) //only one parameter of type String
• Programmer must display the fractions in their conventions such as
  • 2/4 should be displayed as 1/2 (note: gcd)
  • 3/1 should be displayed as 3
  • 5/2 should be displayed as 2 1/2
  • 4 should be displayed as 4/1
• Furthermore, programmers must correct the typos of unique interpretation such as
  • l (lowercase of capital L) is 1
  • O (capital o) is 0 (zero)
