Ruby String Integer Scanning

Question

Is there a Ruby equivalent of the Java Scanner?

If I have a string like "hello 123 hi 234"

In Java I could do

Scanner sc = new Scanner("hello 123 hi 234");
String a = sc.nextString();
int b = sc.nextInt();
String c = sc.nextString();
int d = sc.nextInt();

How would you do this in Ruby?

Answer 1

Multiple assignment from arrays can be useful for this

a,b,c,d = sc.split
b=b.to_i
d=d.to_i

A less efficient alternative:

a,b,c,d = sc.split.map{|w| Integer(w) rescue w}
