 # ArrayList Fraction Objects in Java

## Question

The Program:

You need to create an ArrayList with 10 Fraction objects. Each fraction should be created with a random numerator and denominator between 1 and 100. The fractions should be printed to the screen, sorted from low decimal value to high, then, reprinted to the screen as a sorted list of fractions.

Sample Output: (Your fraction values will vary)

Before sort:
0 The fraction is 67/37 Decimal value is 1.81
1 The fraction is 97/77 Decimal value is 1.26
2 The fraction is 40/53 Decimal value is 0.75
3 The fraction is 5/47 Decimal value is 0.11
4 The fraction is 15/18 Decimal value is 0.83
5 The fraction is 41/33 Decimal value is 1.24
6 The fraction is 22/74 Decimal value is 0.30
7 The fraction is 40/71 Decimal value is 0.56
8 The fraction is 32/93 Decimal value is 0.34
9 The fraction is 99/27 Decimal value is 3.67

After sort:
0 The fraction is 5/47 Decimal value is 0.11
1 The fraction is 22/74 Decimal value is 0.30
2 The fraction is 32/93 Decimal value is 0.34
3 The fraction is 40/71 Decimal value is 0.56
4 The fraction is 40/53 Decimal value is 0.75
5 The fraction is 15/18 Decimal value is 0.83
6 The fraction is 41/33 Decimal value is 1.24
7 The fraction is 97/77 Decimal value is 1.26
8 The fraction is 67/37 Decimal value is 1.81
9 The fraction is 99/27 Decimal value is 3.67
