Question

I am taking input from a file in following format:

(int1,int2) (int3,int4)

Now I want to read int1, int2, int3 and int4 in my Java code.
How can I do it with regular expression matching in java. Thankx.

Answer 1

String[] ints = "(2,3) (4,5)".split("\\D+");
System.out.println(Arrays.asList(ints));
// prints [, 2, 3, 4, 5]

To avoid empty values:

String[] ints = "(2,3) (4,5)".replaceAll("^\\D*(.*)\\D*$", "$1").split("\\D+");
System.out.println(Arrays.asList(ints));
// prints [2, 3, 4, 5]
