Im trying to create a program in java that takes the input o

I\'m trying to create a program in java that takes the input of a user as fraction and uses the QuickSort method to sort these equations. I created a fraction class, a QuickSort class and main.

My question is:

In main, how do i take the user input with \"/\" in it (i.e. 1/2 4/5 0/2...). Is there a way to split all the string input into an array, then read only the integers? Or how am I supposed to do that?

Solution

You can use the Scanner class with delimiter as \'/\' to read the numerator part, and then set the delimiter as whitespace to read the denominator part. Here is the code:

public static void main(String[] args) {

Scanner s = new Scanner(System.in);

Pattern whitespace = s.delimiter();

int numerator = 0;

int denominator = 0;

while(scanner.hasNext()) {

s.useDelimiter(\"/\");

numerator = s.nextInt();

s.useDelimiter(whitespace);

denominator = s.nextInt();

# Consume numerator and denominator here

# For quicksort I imagine you would want to store them in an array

}

scanner.close()

}
