Java fractions

Question

So I am making a method for adding fractions, but the user input begins as such:

String frac1 = “5/6”;
String frac2 = “1/7”;
String frac3 = “-2/9”;

How can I get java to read the String and interpret it as 2 seperate int variables (numerator, denominator)? I’m assuming parsing but I’m totally boggled how to break up the string and especially how to interpret negative values for calculating 2 fractions’ sum

Answer 1

You can use String.split for get numerator and denominator of fraction then use Integer.valueOf (or Integer.parseInt) for detect if either are valid numbers and get their values like integer

Answer 2

Ues regex to split the input to nom/denom

Answer 3
